Alaska Cruise Weather: May-July Overview

Erica Silverstein

• February 8, 2021

Alaska is known for its unpredictable and often erratic weather, so many travelers hesitate over which month to book their sailing. 

While winter months carry a certain magical allure, most opt for spring or summer trips due to vibrant landscapes, extended daylight hours, and milder temperatures. 

It’s also during this period that travelers can indulge in fishing and wildlife-viewing opportunities.

Check out our guide to Alaska cruise weather for May, June, and July. In addition to monthly stats, discover the other seasonal variations that can help you pick the perfect time to cruise. 

Alaska Cruise Weather: May

In May, Alaska cruise temperatures average between 40 and 55 degrees Fahrenheit. 

May tends to be slightly rainier than June and July, with a slight chance of snow earlier in the month. 

Ketchikan, a popular stop for cruise ships, is one of the rainiest places in North America. It averages about 9.5 inches of rain in May. So if you’re cruise includes a visit to Ketchikan, it wouldn’t hurt to pack your rain gear. 

Ketchikan averages 16 hours of daylight in May; you’ll get even longer days as you travel north to Anchorage and still more if you take a cruise tour up to Fairbanks. 

However, daylight hours in May are a few hours shorter than what you’ll experience if you travel around the spring equinox in late June. 

Expect to see plenty of snow-capped peaks in May. If you travel up into the hills or mountains on a shore excursion, it’s common to find snow still on the ground. As such, you’ll want to pack waterproof hiking boots and warm, waterproof layers (don’t forget gloves and hats) to handle any wet or chilly spring weather. 

Mosquitos aren’t a problem in May. They’re in the summer, so you don’t have to worry about pesky insects while enjoying your vacation. 

If you’re planning a cruise tour to Denali National Park and Preserve, it’s worth noting that the bus service doesn’t begin until late May. The road through the park is only partially open until early June. 

For nature lovers, you’ll be glad to know that May marks the beginning of the salmon-fishing, whale-watching, and wildlife-viewing seasons. 

Although you can spot whales and go fishing any time during the Alaska cruise season, late May and early June are considered the best for seeing mammals because this is when moms and babies search for food. 

If budget is as big a concern as Alaska cruise weather, May is one of the cheapest months to sail due to shoulder-season discounts.

Alaska Cruise Weather: June

If you’re planning an Alaska cruise in June, temperatures average a low of 45 and a high of 62. 

June is tied with July as the least rainy month, with Ketchikan receiving an average rainfall of less than 7.5 inches.

Alaska cruise weather in late June is some of the best, with 18 hours of daylight and plenty of sun. If you’re lucky, it might even get warm! 

With drier ground in June than in May, Alaska cruisers can start to hike in earnest. 

Whether on your own or with a guide, be sure to pack appropriate gear, such as backpacks with bear bells, water bottles, snacks, and—most importantly—bug spray. The mosquitos start being a nuisance in June. 

For other shore excursions, layering is your best bet. You might need a fleece jacket in the morning but find yourself stripping down to a T-shirt by early afternoon. A packable rain jacket is always good to have on hand since you never know when you’ll get caught in a summer squall. 

The warmer Alaska weather makes June (and July) the best times to see calving glaciers during scenic cruise days. 

June is also one of the best months for whale-watching; late June and early July are the best times for bear-spotting excursions. 

Because of the fine Alaska weather in late June, it’s an excellent time to plan a cruise tour to Denali. The roads are open, days long and dry, and there’s an increased chance of seeing active wildlife.

Cruise fares in June will be higher than in May but better than in the prime summer months.

Alaska Cruise Weather: July

July offers the best Alaska cruise summer weather. It has the least rain (less than 7.5 inches in Ketchikan), long days (17 to 18 hours of daylight), and a warm climate. Temperatures average a low of 48 and a high of 65.

Pack your sunglasses, sunscreen, and your bathing suit for a top-deck dip after your shore tour. Despite the positive forecast, you’ll still want to pack light layers and rain gear that you can don for glacier viewing or visits, forested hikes, or the always-possible rain shower.

Fishing enthusiasts will do their best cruising in July since most types of salmon are running during this month. As with June, it’s an ideal month for wildlife viewing, whether you seek out bears, moose, or Humpback whales.

The glaciers along your route will be cracking like mad, so make sure your July cruise swings by Hubbard Glacier, Glacier Bay, or other scenic cruising destinations. 

You’ll have the full range of cruise tour destinations open to you if you travel in July. But be warned: Cruise fares average the highest this month because the Alaska cruise weather in July is so nice, and more families are traveling because school is out for the summer.

Frequently Asked Questions

What is the best time to cruise alaska .

The answer entirely depends on your travel goals.  In general, the best time to cruise Alaska is from July to September due to milder weather and longer daylight hours. During these months, tour destinations and attractions are open and fully operational, so you can enjoy the full Alaskan experience. 

However, May and June also come with their own perks. For one, they’re excellent months for wildlife viewing. The landscape becomes alive with hundreds of migratory birds, and you’ll have a good chance to spot bears, whales, and other wildlife. 

Furthermore, May and June bring competitive pricing for cruises compared to the peak season in July. This can be advantageous for budget-conscious travelers. 

What is the best time of year to see the northern lights in Alaska cruise?

Northern lights in Alaska usually appear during the aurora seasons, which typically fall in April, August, and September. It’s less likely to occur between May and July due to the extended daylight hours and the midnight sun

Can I still see glaciers during an Alaska cruise from May to July?

Yes! In fact, most glacier excursions are best done in summer and early fall months, which coincidentally falls between May and July and extends till September. Glacial activities, such as calving, are more pronounced during these periods due to warmer temperatures.

Alaska Cruise Weather by Month

The Alaska cruise season generally runs from May to September, with occasional cruises in April and October.

The below chart shows the Alaska cruise temperatures you can expect on the inside passage, along with rainfall and hours of daylight:

Alaska Cruise Weather in May

• Highs : 55°F
• Lows : 40°F
• Average Rainfall : 3.48 inches
• Hours of Daylight : 16.5 hours of daylight

Many cruise ships begin their summer deployments to Alaska in May before peak season begins in June.

The Alaska cruise weather in June is fairly cool, but it has the least amount of rainfall during the Alaska cruise season. You can expect Alaska cruise temperatures in May to have lows of around 40 and highs of around 55 degrees Fahrenheit.

May is one of the best times to visit Alaska for dry weather, fewer crowds, and lots of wildlife.

During May, you’ll find several whale species along Alaska’s inside passage. By this time of the year, most of the whales will have completed their migration from the warm waters of Mexico to Alaska, where they will spend the summer.

Spring is also the time to spot newborn wildlife.

You can expect to see lots of snow-capped mountains, and there are fewer insects and mosquitos.

Alaska Cruise Weather in June

• Highs : 60°F
• Lows : 45°F
• Average Rainfall : 3.36 inches
• Hours of Daylight : 18.1 hours of daylight

Early June is when the Alaska cruise season kicks into high gear. The warming weather allows cruise ships to travel through the Arctic waters providing unique opportunities for passengers.

The Alaska cruise temperature is warmer in June, with lows of 45 and highs in the low 60 degrees Fahrenheit. Make sure to pack insect repellant when you visit Alaska in June, as mosquitos and other insects can become a nuisance.

The warm weather makes it one of the best times to witness the calving of glaciers.

You can expect 18-20 hours of daylight in June, providing lots of time to enjoy the Alaskan wilderness and abundant wildlife.

June is one of the best months for wildlife sightings, with caribou, black bears, mountain goats, moose calves, and even polar bears out and about.

Alaska Cruise Weather in July

• Highs : 65°F
• Lows : 50°F
• Average Rainfall : 4.14 inches
• Hours of Daylight : 17.3 hours of daylight

July is the peak season for Alaska cruises and provides the best Alaska cruise weather and wildlife opportunities. This month has some of the warmest weather, longest daylight hours, and the largest number of tourists.

Temperatures in July average from the high 40s to 65 degrees Fahrenheit.

The warm weather and long hours of sunlight mean you’ll want to pack sunglasses and sunscreen. You should still wear layers when visiting the port, but if you’re planning active shore excursions like hikes or glacier walks, you’ll want to stick with lightweight clothing.

July is an ideal month to visit for salmon fishing, cultural festivals, bear viewing, and small-town exploring. With the popularity of July cruising, cruise prices are at their highest.

Despite having the best weather, Alaska’s weather in July is very unpredictable. You’ll want to pack for all kinds of weather and wear a lightweight rain jacket.

Alaska Cruise Weather in August

• Average Rainfall : 5.37 inches
• Hours of Daylight : 15.2 hours of daylight

August is when the Alaska cruise season begins to wind down. During this month, you can expect the weather begins to cool, higher rainfall, and gorgeous fall landscapes.

You may be able to find some deals towards mid-August, but expect full fares for the most part.

The chance of rain during this month is over 50%, so you’ll want to pack plenty of waterproof gear – including waterproof shoes and wool socks.

Alaska Cruise Weather in September

• Average Rainfall : 7.54 inches
• Hours of Daylight : 12.4 hours of daylight

As school returns to session, cruise prices dip and provide travelers with last-minute bargains to take an Alaskan cruise.

The temperatures in September are slightly cooler, with highs of 55 and lows around 40 degrees fair height. September is also the rainiest month of the cruise season. So be prepared to pack lots of rain gear.

September also sees fewer crowds than in the summer. However, the shoulder season has become more prevalent in recent years, making great deals harder to find. Knowing when to book your cruise can help you save money on your trip.

Due to the shorter daylight hours, September provides the best opportunity to see the Aurora Borealis from an Alaskan cruise.

The Best Time to Cruise Alaska: A Month-by-Month Guide

Sharing is caring!

Choosing the best time of year for an Alaskan cruise can be challenging. From month to month, the weather, wildlife, and your chances of viewing the mesmerizing Northern Lights vary greatly.

Since I grew up in Alaska, I’m a fan of just about everything in the Land of the Midnight Sun. I also know that your experience can vary widely depending on the month you choose to visit Alaska.

Which raises the question…

When is the Best Time of Year to Cruise to Alaska?

The abbreviated Alaskan cruising season goes from May to September. Although you’ll find the highest number of travelers visiting Alaska during the peak cruising (and fishing) months of July and August, the ideal time for your Alaskan cruise depends most on your personal priorities.

In this post, I share a month-by-month guide about the best time of year for an Alaskan cruise. I’ve included tips on the weather, wildlife, daylight, and the general experience you’ll have each month of the Alaska cruise season to determine when to set sail for the 49th state.

Alaska Cruise Season

The cruising season to Alaska is shorter out of necessity. Weather, ocean conditions, and limited sunlight make winter cruising to Alaska impossible.

For major cruise lines, the Alaska cruise season runs between May and late September, including Viking and Disney.

Many cruise lines also have limited early cruise ships departing for Alaska in April. Norwegian Cruise Lines has the first departures of the season in early April from Seattle.

Holland America Princess, and Royal Caribbean have Alaskan Inside Passage cruises departing from Vancouver at the end of April. Carnival has 14-day Alaskan cruises departing from Seattle and Long Beach in late April.

Alaskan Cruise Month-By-Month Guide

What to Expect on an Alaskan Cruise in April

Spring in Alaska is a unique experience. The benefits of cruising in April include less expensive pricing, fewer tourists, and less crowded ports. Here is a breakdown of other important considerations for an April Alaskan cruise.

Locals typically call the months of April and May “break-up” because the snow and ice begin to break apart and melt after the long winter. What does this mean for tourists? Snow and mud! In April, mountains will still be snowy, and high temperatures will max out in the upper 40s for most cruise ports.

April marks the beginning of the dry season for Southeast Alaska. However, it’s important to remember that this area is part of the world’s largest temperate rainforest.

The average rainfall in Juneau during the month of April is 2.77 inches. Although the rain isn’t convenient, it is the reason for the lush vegetation you enjoy.

Be sure to pack high-quality rain gear for excursions along with warm, layered clothing and a hat and gloves. Many early spring cruisers also pack a winter coat.

Because of its latitude, Alaska experiences extremes in daylight in the summer and darkness in the winter.

On Winter Solstice (December 21 or 22), the state breaks out of its winter hibernation and begins gaining a few minutes of sunlight each day. By the time Summer Solstice occurs (June 20,21, or 22), travelers to Juneau, Alaska, a common port, will experience a day with 19 hours of sunlight.

In April, towns along the Inside Passage will have just over 15 and a half hours of sunlight and will be gaining daylight every day.

Since the skies do still get dark during this month, there is a slight chance that you’ll be able to view the Northern Lights on an Alaskan cruise in April. Peak viewing of the Aurora Borealis happens between November and March, but on a clear night with lots of solar activity, you have a shot at this once-in-a-lifetime viewing experience.

When it comes to Alaskan cruises, balcony cabins come at a premium. You can save money by opting for an inside or an oceanview cabin. However, the views and ability to go sightseeing from your room on ocean days make the higher price worth it.

If you purchase a balcony cabin, you can take advantage of the long days in the Land of the Midnight Sun. As your ship reaches the Inside Passage, the early morning views outside of your room are breathtaking.

There are plenty of animals to see while cruising to Alaska. Arguably, the biggest draw is the marine animals, with opportunities to see pods of humpback whales, gray whales, orcas, sea lions, sea otters, and more.

There are also amazing birds, including bald eagles and land animals like mountain goats, Dall sheep, and brown and black bears.

Although gray whales are more elusive than their humpback cousins, April is your best chance to spot them as they migrate from their winter breeding grounds in Baja, Mexico, to feed in the waters inside the Interior Passage of Alaska.

Orca whales (which are actually members of the dolphin family) are a fairly common site on an Alaskan cruise. “Resident” orcas (who stay near shore and feed on fish) are easy to spot and fun to watch from the cruise ship or on a whale-watching excursion.

General Experience:

Choosing to cruise in the early spring of Alaska will impact your experience. Less travelers might sound appealing, but many port towns aren’t fully “tourist operational” until late June when summer workers start to arrive.

An April sail date is one way to save money on your Alaskan cruise. Just expect cooler weather, fewer wildlife viewing opportunities, and less active ports with some shops that are still shuttered.

What to Expect on an Alaskan Cruise in May

Cruising to Alaska in May is still considered early in the season. As the month progresses, temperatures rise slightly, and daylight hours increase.

While prices in the early season are generally less expensive, your experience during a May cruise will look different from during the high season in July and August. Here is what you’ll find in Alaska in May.

Alaska will still be emerging from winter during May. The high temperature in May in the capital city of Juneau, averages in the mid-50s, with lows in the 40s.

In most Alaska ports, rainfall occurs about 15 days of the month. You’ve got about a 50/50 chance of getting rained or snowed on during excursions. You’ll be very happy if you purchase a quality raincoat and pack clothing you can add or remove in layers.

A hat, gloves, and a winter coat would be a good idea to pack for an Alaskan cruise, especially if you depart in April, May, or September.

Alaska is still gaining sunlight as the Summer Solstice approaches, so you’ll experience longer days during your May cruise.

At the beginning of the month, sunrise in Juneau begins at 5:00 a.m., and sunset is at 8:47, resulting in 15 hours and 47 minutes of daylight. As May closes, the days are even longer, with the sun rising in Juneau at 4:00 a.m. and setting at 9:49 p.m. (almost 18 hours of daylight!).

Another thing to keep in mind when deciding the best month for your Alaskan cruise is wildlife viewing opportunities.

Salmon usually begin their long journeys home to spawn in May, but they come in different waves or “runs.” You might have a chance to view bear feeding on salmon this early in the springtime, but your chances are better later in the summer.

There are exciting marine animals that you can see this early in the Alaskan springtime.

Alaska’s Stellar sea lions are an impressive sight for cruisers. Because they don’t migrate, you have a great chance of viewing these 1000+ pound, 10-foot-long animals on rocks near the shorelines as you cruise. Be sure to listen for their signature roar.

There is also potential for viewing orcas, gray whales, and walruses.

May is an excellent cruising month for birdwatchers as migratory songbirds start to arrive in Alaska and seabirds gather in their nesting spots or rookeries. Keep an eye out for my favorite, the ever-adorable puffins, Arctic terns, cormorants, and bald eagles.

May is a practical choice for Alaskan cruisers who are on a limited budget but want to have slightly warmer and drier weather and more chances to see wildlife. Your views will likely include snowy mountains, but they are gorgeous nonetheless.

Expect less activity and fewer shop openings in some smaller port towns in May since most summer workers are in college and won’t arrive until June.

What to Expect on an Alaskan Cruise in June

Things start hopping in Alaska in June. Summer workers (typically college students) begin to arrive for the peak tourist season, and shops and restaurants open for the summer.

As the temperature warms up, the snow on the ground in port towns melts, and more wildlife begins emerging from their winter dens.

Because school is often still in session for younger children in May and June, taking an Alaskan cruise in the early Spring/Summer is a good choice if you prefer fewer children on board.

In the Lower 48, temperatures in June start to heat up, not so much in Alaska.

While temperatures are warmer and the snow is typically gone at lower elevations, the highs in Juneau average in the low 60s, with lows in the upper 40s.

Temperature is relative, so don’t be shocked if you see an Alaskan sporting shorts and a tank top in June. The 60s can feel downright tropical after winter temperatures in the 20s and 30s.

Rainfall slows down a bit in June, with about 13 days of the month having some precipitation.

Packing-wise, you’ll still want to bring a raincoat, but you can probably leave your winter coat home if you are cruising in June.

It is remarkable to experience Alaska on or around the summer solstice. The amount of daylight increases as you travel northward, but even Juneau’s 19-hour solstice day, with the sun rising at 3:48 a.m. and setting at 10:09 p.m., is a fantastic experience.

If you are in port, you’ll get to see how Alaskans take advantage of the Midnight Sun with locals out biking, hiking, and fishing at all hours of the night.

You’ll also have more hours to look for wildlife from your room window or veranda.

If you have an exterior room and are sensitive to light while sleeping, a sleeping mask will help you rest during these long days.

Humpback whales are the most commonly seen whale in Alaska. They begin migrating from Hawaiian waters in the springtime to feed in the nutrient-rich Alaskan waters.

While it is possible to see humpbacks during the entire cruise season (April-October), your best bet for whale watching will be the months of June, July, and August. They are quite an awe-inspiring sight to see as they travel in pods, breech, and feed.

This is also the time of year when King Salmon runs both begin and end. If you are an angler, there is nothing like hooking and reeling in a King. With an average size of 24 to 36 inches and weighing 10-50 pounds, you’ll finally have a true fishing story worth telling.

If you cruise to Alaska in June, you can expect warmer and drier temperatures, fewer children onboard, increased wildlife sightings, and more cruise offerings.

June is a smart choice for cruisers who don’t want to travel during peak season but want more opportunities.

What to Expect on an Alaskan Cruise in July

Weather is a pretty big consideration when it comes to booking an Alaskan cruise. Temperatures can be quite chilly on deck and in ports of call. If you have a low tolerance for cold weather, cruising Alaska during the warmest months of July and August is a better choice.

July and August are considered peak seasons to cruise to Alaska for good reason. These are the months when all good things combine to create the optimal Alaskan experience.

That being said, the weather and wildlife in Alaska are notoriously unpredictable. You could book a cruise in July and never get above the 50s. You might take a float plane to see bears and, sadly, not see a single one.

My advice is to pack plenty of warm (and waterproof) layers , expect the unexpected, and find joy in whatever experience you get.

The weather in July only trends slightly warmer than June. The average July temperature in Juneau is 64 degrees, with an average low of 51 degrees.

The dry season ends, and precipitation starts to increase in July. Rain falls on average 14 days of the month. Just remember our earlier reminder that you are visiting the world’s largest temperate rainforest and enjoy the lush greenery.

After the Summer Solstice in June, Alaska begins losing daylight with each passing day. While the days are still longer than those in the Lower 48, they are getting slightly shorter throughout July.

In Juneau, the sun rises at 3:54 a.m. at the beginning of July. By the end of July, it starts rising at 4:45 a.m.

Sunsets move to earlier in the night as the month progresses. The sunset on July 1 in Juneau is at 10:07 p.m., and by the end of July, it is at 9:21 p.m.

Although it is getting darker earlier, solar activity is not at its peak in the summer, so your chances of viewing the Northern Lights in July are slim to none.

July is a spectacular month for viewing wildlife in Alaska. Not only are humpback whales, orcas, sea lions, eagles, and seabirds easier to see as they feast in the nutrient-rich summer waters, but the likelihood of seeing the indomitable Alaskan brown, black, and Kodiak bears increase as they focus on fattening up on migrating salmon.

Small-ship Alaska cruise lines like American Queen Voyages and Uncruise can go further into narrow passages and get closer to shoreline wildlife like Dall sheep and bears.

If bear viewing is high on your bucket list and you are traveling on a bigger cruise ship, look for a float plane excursion that will take you to where the bears feed.

July is filled with opportunities to see the stunning wildlife of Alaska while enjoying milder temperatures.

July also brings the highest number of tourists to Alaska. If you cruise to Alaska this month, you can enjoy more shop and restaurant options in port towns but expect things to be slightly more crowded.

What to Expect on an Alaskan Cruise in August

August is a delightful time to cruise to Alaska. You’ll enjoy wildlife viewing, warmer temperatures, and daylight returns to more typical hours. However, the dry season has ended, so rainfall will begin to increase as the month progresses. 

For cruise itineraries in Alaska, August high temperatures will be somewhere in the upper 50s and low 60s. We’ve reached the pinnacle of summer temperatures, and the rainier season has just begun.

Juneau gets about 17 days of rain in August, so a high-quality raincoat is essential.

With lows in the 50s, you don’t need to pack a winter coat and hat, but be sure to include warm, wicking layers to keep your temperature steady.

By the end of August, the sunrise and sunset times in Alaska are pretty close to “normal” times for most states in the USA. You might feel like you aren’t getting the true Alaskan “Midnight Sun” experience this month. 

In Juneau, on August 31, the sunrise is at 5:52 a.m., and the sunset is at 8:01 p.m.

The loss of daylight does mean you could see the Aurora Borealis while cruising to Alaska in late August. The best time to see the Northern Lights is between late August and April, typically peaking in March.

Unfortunately, seeing this supernal show of sun activity is not a given. Overcast skies are common in Alaska and block the Lights, and the solar activity that creates the phenomenon is unpredictable. You can increase your chance of seeing the Northern Lights by asking crew members if you can get placed on a list that will be notified when, as we say in Alaska, “the lights are out.”

In August, the wildlife can sense that winter is on its way, and activity picks up to prepare for the months of cold, snow, and darkness.

You might see bears that are continuing to fatten up before hibernation. Humpback whales have yet to begin their migration to warmer waters, so you will still be able to see them, especially in early August.

Seabirds will still be feasting on fish. You also might see fuzzy harbor seal pups and sea lion pups (born in June and July) warming themselves on rocks with their mothers. Add high-powered binoculars to your Alaska packing list to ensure that you get to see all of the wildlife possible.

General Experience :

You can’t go wrong with a cruise to Alaska in August. Not only is it your best shot for warmer weather, but you’re also sure to see a good amount of the wildlife Alaska is famous for.

Warmer weather in Alaska also has an unexpected bonus for cruisers in the form of glacial calving.

Glaciers are a natural wonder that no photographs can do justice. Until you have experienced the majesty of an ancient river of ice in an unparalleled blue, it is hard to imagine!

Every Alaskan cruise includes at least one glacier viewing stop. The warmer the weather, the better your chance to view a once-in-a-lifetime occurrence called “calving.” This is when a large chunk of the glacier separates in a giant icy landslide.

Not only is the cracking sound shocking, but the calving also produces a giant wave of water and captivating icebergs. July and August are prime time for viewing glacier calving on an Alaskan cruise.

What to Expect on an Alaskan Cruise in September

April, May, and September are considered shoulder seasons for cruising to Alaska. Shoulder season is the time between peak season and off-season when there are fewer cruisers and lower prices.

A September cruise has its benefits, including less crowding and cheaper prices. However, a cruise this time of year will also slightly decrease your chance of viewing wildlife and make for sleepier ports of call because most summer workers return home for college.

In Alaska, we measure the return to winter by how far up the stalk Fireweed flowers have bloomed. By September, the blooms are most certainly to the top as winter rapidly approaches.

High temperatures in September in Juneau hover around the upper 50s with lows in the mid-40s, though, so it is still an enjoyable time to visit.

Precipitation increases to 19 days of the month, so pack a raincoat with a hood (you’ll be grateful to have it!).

There is a chance you will see some snow, so a winter coat, gloves, and a hat are a smart addition to your packing list.

In September, the scale now tips towards later sunrises and earlier sunsets in Alaska. By the end of September, there are less than 12 hours of daylight in Juneau.

Cruising in September will give you the highest chance of viewing the Aurora Borealis on an Alaskan cruise. You won’t want to miss this indescribable sight, so watch for clear night skies and set an alarm to go on deck (or on your balcony) for potential middle-of-the-night Northern Lights shows.

Gray whales and Humpback whales begin their migration to warmer waters in October and November, so you still have a chance to see them in Alaskan waters in September.

Birds also haven’t started their migration, so you can spot both songbirds and seabirds as you cruise along the coast.

Silver salmon runs are possible in September, but not a guarantee.

September is also an excellent time to witness a towering Alaskan moose. By this time of year, bull moose have a full rack of antlers. With shoulder heights at 6 foot 9 inches and over 1,400 pounds, these massive animals are as dangerous as impressive, so you’ll want to view them from a distance.

Cruising to Alaska in September has many benefits of the peak season (milder weather and good wildlife viewing) with less expensive prices and fewer tourists.

Although the weather will likely include more rain, you have a better chance of viewing the Northern Lights, which might outweigh this drawback.

If your itinerary includes stops in Anchorage, Seward, or Whittier, you might experience rougher seas as you cross the Gulf of Alaska in September.

FAQs About Alaskan Cruises

What is the best time of year to see the northern lights on an alaska cruise.

The peak season to view the Northern Lights or Aurora Borealis is between late August and late April, which unfortunately doesn’t overlap much with the Alaskan cruise season. If the Northern Lights experience is high on your Alaska bucket list, consider a September cruise with more dark nighttime hours and increased solar activity.

How far in advance should you book an Alaskan cruise?

If you are hoping to travel during peak Alaskan cruise season (July and August), you should plan on booking your Alaskan cruise at least one year in advance. The farther in advance you can book your Alaskan cruise, the more options you will have for cruise dates, itineraries, and cabin amenities.

Are the seas rough on an Alaskan cruise?

When traveling from Vancouver in the Inside Passage of Southeast Alaska, the waters are mostly protected and provide smooth sailing. If ports include Anchorage, Seward, or Whittier, cruise ships must cross the Gulf of Alaska, which has notoriously rougher waters. This is especially true after Labor Day.

Cruise Tips for Alaska Weather: Month by Month

If you’re thinking about planning a summer cruise , Alaska may be the perfect destination for you. The Alaskan cruise season lasts from May to October, and the warmest months for travel are typically June, July, and August. Alaskan cruises may seem suited only for people who like extreme weather, but the truth is that the weather in Alaska varies widely based on the region.

Here’s what you can expect each month on your upcoming Alaska cruise along with what you really need to pack.  

Ready to start planning? Explore all Alaska cruises .

Alaska Cruise Weather in May

May brings warmer weather within the cities and towns of the Alaskan inside passage. While it can be freezing cold at times, the weather can also be pleasantly cool. The low temperatures typically range from the mid-thirties to the low forties Fahrenheit, but the highs can get up to the upper fifties.

This month also experiences near constant cloud cover with a good chance of rain on any given day. Travelers get at least fifteen hours of daylight and twilight in May, providing more time for whale watching and other outdoor activities. With low wind speeds, cold temperatures, and precipitation, travelers may want to pack plenty of knit sweaters, a jacket, warm pants, and waterproof boots or shoes.

Alaska Cruise Weather in June

Most of the month of June in Alaska is either cold or pleasantly cool with very cold temperatures being less frequent than in May. The lows can be as low as forty-three degrees Fahrenheit, and the highs can get up to the sixties on average.

Cloud cover and precipitation conditions from May persist throughout June and July, and wind speeds remain low as well. Layers are essential for this type of fluctuating weather, and travelers should be sure to pack waterproof jackets and shoes for rainy moments, cardigans or light sweaters, and other warm clothes like jeans, long skirts, and tights.

Alaska Cruise Weather in July

July is known as the hottest month in this section of Alaska with the hottest day of the year falling on July 9th. Temperatures range on average between fifty and sixty degrees with mostly cool afternoons and evenings and chilly mornings and mid-day hours.

The late nights and early mornings can be very cold, but these are also the hours when most people are asleep in their cabins. Travelers cruising to Alaska in July should be sure to pack plenty of layers along with some waterproof outerwear, but they should pack light, removable layers to adjust to the warmer temperatures of the afternoons.

Alaska Cruise Weather in August

August brings a gradual decrease in temperatures again, but it is still one of the hottest months of the year in this region. Temperatures during this month usually range from the mid-forties to the low sixties, and days are typically cool or chilly.

Like July, nights and early mornings can be very cold, so late nighters and early risers should be prepared to bundle up for icy temperatures. Plenty of layers are also essential in August, and travelers should be sure to pack waterproof jackets, shoes, and bags as August and September are among the rainiest months of the year.

Alaska Cruise Weather in September

September is one of the last months of the cruise season in Alaska and it is also one of the coldest, with temperatures staying in the low to high forties on average. As the month advances, the temperatures drop lower and lower, and the nights and early mornings can be bitterly cold.

The abundant cloud cover and frequent rain make the landscape all the more beautiful, but visitors should dress properly for a better overall experience. Travelers still get at least twelve hours of sunlight for excursions and deck activities, but they should pack thick pants, knit sweaters, and insulated shoes to combat the cold along with waterproof rain gear.

Alaska Cruise Weather in October

October in Alaska can see lows can be as low as 28° Fahrenheit, and the highs can reach up to 40° Fahrenheit. You can also expect more precipitation, which can result in some snowy weather.

Both September and October are ideal times to see the stunning Northern Lights, otherwise known as aurora borealis displays. The best times to look is between Midnight and 2am.

While Alaska might be colder than other summer vacation spots, it offers unique experiences that can’t be found anywhere else. These include sightings of wild orcas , sea lions, and humpback whales and riding one of the world’s longest ziplines.

You’ll also have a chance to visit the incredible Butchart Gardens, witness glaciers, pan for gold , hike through temperate rainforests, and much more. If you’re prepared for the weather and pack the right attire for your destination, nothing can get in the way of having a good time.

Alaska cruise in May can be perfect! (pics!) + things to do 🏔 early May and mid-May weather and wildlife?!

Is May too early for an Alaska cruise?!

Well, surely it depends on what you’re looking for.

For example, it seems like May is still early for whale watching.

I still did see whales in May in several cruise ports, but it seems summer is more prime whale watching in Alaska.

And that goes for basically all wildlife.

Prime wildlife watching in Alaska seems to be in the summer.

So if wildlife watching is priority number 1 for you during an Alaska cruise, then May might be too early for you.

But otherwise…

If you are after Alaska landscape, then May can be a perfect time for an Alaska cruise!!

Before I left for my early season Alaska cruise, I had gotten the impression from reading things online that you actually have a better chance of better weather in May.

And, that is basically what happened.

The vast majority of my time in Alaska in May, there was good weather.

I was not really surprised, since I expected good weather by going to Alaska in May. 😂

So I was a bit confused when there were locals in several of the cruise ports who made it sound like good weather was unusual, even in May. 🤔

I asked a Glacier Bay National Park ranger about this, and she indicated that May in Glacier Bay tends to be one of the months that is more dry and sees more sun, so maybe I was just reading about Glacier Bay. 🤔

In any case, when I went to Alaska in May, the weather on the vast majority of Alaska days was pretty good.

Even Ketchikan, which the internet will tell you is always rainy, was sunny the 2 times I went in May.

And the one pretty terrible weather day I had in May, it was actually pretty funny because it was the first Alaska day I had, and it was super rainy, super windy, and super cold!

And so… it was like a perfect “welcome to Alaska!!!” 🤣

So I guess it’s true.

Anything goes in Alaska!

And that includes Alaska in May!

As “they” say, weather can change quickly in Alaska!

Pictures of Alaska in May

Of course, every year is different since it’s all weather dependent.

But here is what an Alaska cruise in May looked like in 2023!

May 2: Hubbard Glacier scenic cruising sea day

• May 3: Icy Strait Point
• May 4: Juneau
• May 5: Skagway

May 6: Glacier Bay National Park scenic cruising sea day

• May 7: Sitka
• May 8: Ketchikan
• May 15: Ketchikan
• May 16: Juneau
• May 17: Skagway

May 18: Glacier Bay National Park scenic cruising sea day

• May 19: College Fjord scenic cruising sea evening
• May 20: Whittier

I did 2 Alaska cruises in May:

• Alaska cruise from Vancouver round trip
• Vancouver to Anchorage cruise one-way

Another thing to consider for an Alaska cruise in May is that it might still be too early in the season to reach some spot because of ice.

It seemed like it was questionable if we were going to make it to Hubbard Glacier.

I think the captain had announced that our cruise ship was the first of the Alaska cruise season to go to Hubbard Glacier, so there were no ice reports.

But, we ended up being able to make it to Hubbard Glacier!

There was ice, but it wasn’t enough to keep the cruise ship from reaching Hubbard Glacier!

And, the ice on the way to Hubbard Glacier made it look really pretty!

Cruising to Hubbard Glacier means cruising through Yakutat Bay and Disenchantment Bay to get to Hubbard Glacier.

May 3: Icy Strait Point cruise port

My plan for Icy Strait Point cruise port:

• morning: Icy Strait Point whale watching tour ( Icy Strait Point Whale Adventures ) 8:45am to 11:45am
• afternoon: Walk around Icy Strait Point on my own 

Early May seems to still be early for whale season, so I wasn’t even sure if I’d have a chance to see whales.

The day before, it seems like they saw quite a few whales, but on the day I went it seems like there weren’t as many.

That’s okay, because I had managed my expectations since May wasn’t prime whale watching season in Alaska.

At the very least, it was boat ride in Alaska in May!

Still, I did get to see a whale tail pretty close from the boat, and it was my first time seeing a whale tail like that, so that was the highlight of the whale watching tour in Icy Strait Point!

May 4: Juneau cruise port

My plan for Juneau cruise port:

• morning + lunch: Taku Lodge Feast & 5-Glacier Seaplane Discovery with Taku Lodge Wings Airways (Princess shore excursion) 9:30am to 1pm
• afternoon + evening: Mendenhall Glacier and Nugget Falls on my own

May 5: Skagway cruise port

My plan for Skagway cruise port:

• morning: White Pass Rail & Klondike Highway (Princess shore excursion) 8:15am to 12pm
• afternoon: Glacier Discovery by Helicopter with Temsco Helicopters (Princess shore excursion) 2:15pm to 4:15pm

May 7: Sitka cruise port

Another gloomy day in Alaska in May!

But it was the first real bad weather day I had since that very first Alaska day!

May 20: Whittier disembarkation day

My plan for Whittier disembarkation day:

• get off the cruise ship as late as possible (9:30am)
• 26 glacier boat tour during the day

Join us as we navigate through the seasons and unveil the secrets of when to book your Alaska cruise for an experience that will exceed your wildest expectations.

Key Takeaways

• Consider the Weather: Choose mid-June to August for warmer temperatures and longer daylight for optimal sightseeing.
• Prioritize Wildlife Spotting: Plan your cruise from May to September, with peak whale and bear sightings in July and August.
• Price and Crowds: May and September offer lower prices and fewer tourists, but some activities may have limited availability.
• Peak Season Advantages: Opt for May to September for longer daylight hours, ideal wildlife viewing, and vibrant onboard atmosphere.
• Shoulder Season Benefits: May and September provide a tranquil experience with fewer crowds and affordable prices.
• Off-Peak Cruises: Consider cruising in May and September for a quieter journey but be prepared for variable weather and shorter days.

Evaluating the Best Time for an Alaska Cruise

Considering the weather.

Alaska’s weather can greatly impact your cruise experience. Summer, from May to September, is the most popular time to cruise Alaska due to milder temperatures and longer days. However, May and September might be cooler with higher chances of rain. If you prefer warmer weather and more daylight for sightseeing, mid-June to August is your best bet.

Wildlife Spotting Opportunities

For wildlife enthusiasts, the best time for an Alaska cruise is during the summer months when animals are most active. Whales, including humpbacks and orcas, are commonly spotted from May to September, with peak sighting times in July and August. Bears fishing for salmon along the shores are also a common sight in July and August. If witnessing Alaska’s rich wildlife is a priority for you, plan your cruise during these peak months.

Price and Crowds

The timing of your Alaska cruise can also affect prices and crowds. The shoulder seasons of May and September typically offer lower prices and fewer tourists compared to the peak summer months. If you prefer a more budget-friendly option and a quieter experience, consider booking your cruise during these off-peak times. However, be aware that some attractions or activities may have restricted availability during these periods.

By carefully considering the weather, wildlife spotting opportunities, and price variations, you can evaluate the best time for your Alaska cruise. Whether you prioritize ideal weather conditions, abundant wildlife sightings, or budget-friendly options, planning your cruise during the right season can enhance your overall experience and create unforgettable memories of Alaska’s stunning landscapes and wildlife.

Peak Season for Alaska Cruises

Advantages of peak season travel.

Opt for Alaska cruises during the peak season from May to September for a truly unforgettable experience. In these months, you’ll enjoy longer daylight hours, providing ample time for sightseeing and exploration. The milder temperatures during this time make outdoor activities more enjoyable, allowing you to fully immerse yourself in Alaska’s stunning landscapes comfortably.

Peak season also aligns with the best wildlife viewing opportunities. Witness majestic humpback whales breaching the waters in July and August, creating magical moments you’ll cherish forever. Additionally, July and August are prime months for spotting bears in their natural habitat, adding an exciting wildlife element to your cruise.

Another advantage of traveling during peak season is the vibrant atmosphere onboard and at ports of call. With more fellow travelers around, you’ll have the chance to socialize, exchange travel stories, and forge new friendships. The energy and buzz during peak season create a lively ambiance, enhancing your overall cruising experience.

Potential Downsides

While peak season offers numerous benefits, it’s essential to consider potential downsides when planning your Alaska cruise. One drawback is the higher cost associated with traveling during peak months. Prices for cruises, accommodations, and excursions may be higher, impacting your overall travel budget.

Crowds can also be a factor to keep in mind during peak season. Popular tourist spots and attractions may be more crowded, leading to longer wait times and less exclusivity in your experiences. If you prefer a quieter and more serene cruise experience, you may find the higher volume of tourists in peak season a bit overwhelming.

Additionally, booking accommodations and excursions well in advance is advisable during peak season to secure your preferred options. The increased demand for services during this time means that popular activities and tours may get fully booked sooner, requiring you to plan your itinerary meticulously.

Being aware of these potential downsides allows you to make informed decisions when choosing the best time for your Alaska cruise, balancing the advantages of peak season travel with considerations such as pricing, crowds, and advance booking requirements.

Shoulder Season Cruising in Alaska

When considering a cruise to Alaska, exploring options during the shoulder season can offer unique advantages. This off-peak period, usually in May and September, presents both pros and cons that are important to weigh before making your decision.

Pros of Shoulder Season

In the shoulder season, you can experience Alaska’s stunning landscapes in a more tranquil setting. The following benefits await you during this time:

• Fewer Crowds : With a decrease in the number of tourists, you get a more intimate experience of Alaska’s beauty without the hustle and bustle.
• Pleasant Weather : Although slightly cooler than peak summer months, the weather can still be enjoyable for outdoor activities with fewer rainy days.
• Affordable Prices : Cruises and accommodations are often more budget-friendly during the shoulder season, allowing you to enjoy Alaska without breaking the bank.
• Wildlife Sightings : You can still witness a variety of wildlife, such as bears, whales, and eagles, during the shoulder season.

Cons to Keep in Mind

While the shoulder season brings its advantages, there are some considerations to keep in mind before booking your Alaskan cruise:

• Limited Activities : Some shore excursions and activities may have reduced availability during the shoulder season, affecting your itinerary choices.
• Variable Weather : Be prepared for unpredictable weather conditions, which can impact outdoor activities and visibility during your cruise.
• Shorter Days : With fewer daylight hours compared to peak summer months, you may have less time for sightseeing and exploring the ports of call.
• Chilly Temperatures : Pack warm clothing as temperatures can be cooler during the shoulder season, especially during evenings and early mornings.

By weighing these pros and cons, you can make an informed decision on whether the shoulder season is the best time for you to embark on an unforgettable Alaska cruise adventure.

Off-Peak Cruises: A Different Experience

The allure of off-peak cruising.

Embark on an off-peak Alaska cruise for a unique and quieter experience. During the shoulder season in May and September, you’ll find fewer fellow travelers, allowing you to enjoy the stunning landscapes and wildlife in a more serene setting. Imagine sailing through the untouched beauty of Alaska without the hustle and bustle of peak season crowds. Off-peak cruises offer a more intimate and peaceful journey for you to immerse yourself fully in the natural wonders of Alaska.

Challenges and Considerations

While off-peak cruises in Alaska provide a tranquil experience, there are some considerations to keep in mind. Variable weather conditions during May and September could mean encountering cooler temperatures or rainy days. Additionally, with shorter daylight hours compared to the peak season, you’ll have less time for exploration during each day of your cruise. Be prepared for potential changes in the itinerary due to weather, as some outdoor activities may be affected. Despite these challenges, the opportunity to witness Alaska’s beauty with fewer tourists and at a more affordable price makes off-peak cruising an attractive option for those seeking a more laid-back and contemplative voyage.

Special Events and Festivals

Alaska’s cultural events.

When planning your Alaska cruise, consider the vibrant cultural events happening throughout the sailing season. Immerse yourself in the local traditions and celebrations to enhance your overall experience. From May to September, you’ll have the opportunity to participate in various cultural festivals that showcase Alaska’s rich heritage. Here are some highlights:

• Alaska Folk Festival : Held annually in Juneau in April, this festival features live music, dance performances, and arts and crafts exhibitions. It’s a fantastic way to engage with Alaskan music and art.
• Sitka Summer Music Festival : Taking place in Sitka during June, this festival attracts classical music enthusiasts from around the world. Enjoy performances by renowned musicians against the backdrop of Alaska’s stunning scenery.
• Kodiak Crab Festival : If your cruise stops at Kodiak in late May, don’t miss the Kodiak Crab Festival. Indulge in delicious seafood, join the carnival festivities, and experience the local community’s warmth and hospitality.

Natural Phenomena and Their Timing

Alaska’s natural wonders add another layer of magic to your cruise experience. Understanding the timing of these phenomena can help you make the most of your trip. Here are a few noteworthy natural events you may encounter:

• Midnight Sun : During Alaska’s summer months, especially in June and July, you can witness the phenomenon of the midnight sun. Experience daylight even during the late-night hours, offering unique opportunities for activities like midnight hikes or wildlife spotting.
• Northern Lights : If you’re cruising in September, you might catch a glimpse of the mesmerizing Northern Lights. Head to areas with minimal light pollution for the best chances of witnessing this awe-inspiring celestial display.
• Salmon Runs : Depending on the timing of your cruise, you could witness the spectacular salmon runs that occur in various Alaskan rivers from late spring to early fall. Watch these resilient fish make their way upstream, a testament to the wonders of the natural world.

Exploring Alaska’s cultural events and natural phenomena can add depth and richness to your cruise adventure. Embrace the diversity of experiences Alaska has to offer, from immersing yourself in local traditions to marveling at the awe-inspiring wonders of the natural world.

You’ve now explored the best times to embark on an Alaska cruise, from the peak season hustle to the tranquility of off-peak voyages. Each season offers unique experiences, whether you prefer the vibrant atmosphere of summer or the peaceful ambiance of the shoulder months. With a variety of special events and natural wonders to encounter, Alaska promises an unforgettable journey regardless of when you choose to set sail. So, pack your bags, prepare for adventure, and get ready to discover the beauty of Alaska on a cruise tailored to your preferences.

Alaska Cruise Weather - What to Expect

Published: Jan 01, 2021 Last Updated: Nov 30, 2023

Though weather can be hard to predict, especially in Alaska, there are trends that’ll help you know what to expect during your summer cruise. So, check the weather before you pack, but these will give you a guesstimate.

The best time for an Alaskan Cruise is May through with September, with the best weather in June and July. In May and September, you can anticipate a few extra rainy days and slightly cooler (though still pleasant!) temperatures. Note that the best times for whale watching  are mid-June to mid-August, though you can catch them before and after this, too.

Here is the typical weather during Alaska cruise season:

Skagway Cruise Weather  

It’s a little warmer and a little less rainy in the land of infamous  Soapy Smith , with high averages in the upper 50’s and lower 60’s May through September and an average rainfall of 27 inches annually. (Summers with streaks of temps in the 70’s are also not uncommon in Southeast Alaska, so remember a few t-shirts!)

Ketchikan Cruise Weather

Alaska’s “first city” is also widely known as the rainiest, with 153 inches per year. (for comparison, seattle, well-known for it’s rain, only gets about 38 inches) high temperatures during june, july, and august are typically in the mid-60’s. the ‘shoulder’ season of may and september is generally about 5-10 degrees colder..

Alaska Cruise Weather

What to expect and when to visit

Cruise season in Alaska is just five months long, running from May to September, although Holland America Line offers Alaska cruises in late April and early October.

So when is the best weather to cruise Alaska? Keep in mind that Alaska and the Yukon make up an enormous mass of land; in fact, combined they are about half the size of the lower 48 states! As you can imagine, it can be difficult to speak in generalities about the climate for a place so vast. However, we’ve broken down the weather in Alaska by season and area, with advice on what to expect, so you can choose the best time to cruise to Alaska.

Weather In Alaska By Season

Temperatures will be lower in the spring (early May to late June), and the weather a bit more unpredictable, but on the plus side there are fewer visitors in  Alaska  and the prices are likely to be a bit lower. So if you’re on the hunt for some of that famous northern solitude, spring is the time for you. And best of all, the land is bursting back to life after the long, cold winter months. Flowers are blooming, bears are rousing from their slumber, and a sense of renewal permeates the land. So, don’t scratch spring off your calendar just because Alaska’s climate may not be ideal.

Average Spring Temperatures:

• Inside Passage/Southeast; Southcentral; and Interior:  daytime highs in the mid 50s to upper 60s, with low temperatures in the mid to upper 30s.
• Far North/Arctic:  daytime highs in the mid 20s to upper 30s, with low temperatures in the mid-teens to upper 20s.

Summer is the peak season for tourism and considered the best time for Alaska cruises, and for good reason. Running from late June to mid-August, summer has the warmest temperatures, near endless sunlight (approximately 18 hours or more per day!), and the best chances for  viewing wildlife . And with the tourism industry in full swing, you’ll find more services and a seemingly endless list of activities to take part in. But you won’t be alone — more stuff to do and nicer weather in Alaska means more people — and the prices will generally be a bit higher.

Average Summer Temperatures:

• Inside Passage/Southeast; Southcentral; and Interior:  daytime highs in the low 60s to low 70s, with low temperatures in the upper 40s and low 50s.
• Far North/Arctic:  daytime highs in the low to mid 40s, with low temperatures in the lower 30s.

This is when Alaska and the Yukon are enjoying a last hurrah before winter sets in. Running from late August through September, fall in Alaska can feel very much like spring. The temperatures will be cooler and the weather more unpredictable, but, like the spring, prices will often be lower and you’ll have less company. And the Alaska wildlife viewing can rival that of the summer, as creatures great and small are out prepping for the barren, frigid months ahead. With fall comes shorter days, but this isn’t without its advantages. Shorter days mean there is an excellent chance of  seeing the Northern Lights  (Aurora Borealis) in the late evenings.

Average Fall Temperatures:

• Inside Passage/Southeast; Southcentral; and Interior:  daytime highs in the mid 50s to low 60s, with low temperatures in the low 40s.
• Far North/Arctic:  daytime highs in the mid to upper 30s, with low temperatures in the mid 20s.

Each season has its pluses and minuses and the best time to cruise to Alaska depends on what’s important to you. Now that you know what to expect from the weather, peruse  Alaska cruise itineraries .

The best time to cruise Alaska

Alaska is a cruise destination with a limited season. Cruise ships arrive in southeast Alaska in spring, stay the summer and linger only into early fall. The 49th state's snowy, cold and dark winters are not conducive to cruising.

Most cruise passengers will head to Alaska between Memorial Day in late May and Labor Day in early September when temperatures range from slightly chilly to warm during the long daylight hours. Tourist attractions are in full swing, salmon swim upriver, and bears (and humans) have access to fishing.

Some adventurous cruisers will board ships when they arrive in Alaska in April to see the remnants of winter. A few big ships cruise into mid-October for those who want a peek at what life is like in Alaska towns when all other tourists have returned home.

Each month has its advantages, not the least of which is discounted pricing in the spring and fall shoulder seasons. Here is a guide to help you decide when to cruise in Alaska.

After a long winter, Alaska begins to wake up in April — that includes the wildlife. Small-ship cruise lines such as Lindblad Expeditions and UnCruise Adventures have sailings into the wilderness, where you might spot bears emerging from their slumber and admire huge waterfalls fueled by the snowmelt. A few big ships, such as Norwegian Cruise Line 's 4,000-passenger Norwegian Bliss out of Seattle , begin their season this month with discounted early-season pricing.

You may encounter freezing rain or even snow on your April cruise and should expect to tread through the mud. Some tourist facilities — including those at national parks — may still be shuttered for the winter.

On the other hand, you will have the opportunity to observe the change of seasons. Expect crisp mornings with temperatures in the 30s, though by the end of the month, you may find dry weather and temperatures in the 60s. As an added bonus, the skies will be dark at night; if clear, you might spot the northern lights.

Related: The best Alaska cruise for every type of traveler

As someone who has cruised Alaska many times, I love cruising in May when the weather is dry. Locals start emerging from their winter cocoons, embracing the sunshine, and the wildlife does the same. You might spot bears with their cubs, moose with their calves and humpback whales returning from their winter home in Hawaii.

Big-ship cruise lines such as Holland America Line , Princess Cruises and Royal Caribbean ramp up their operations in May, as do Disney Cruise Line and small-ship and luxury lines. Early season deals might be available.

Attractions and shops will switch to peak-season hours at the end of the month; Denali National Park and Preserve will switch into summer mode in May. You'll find those who work in tourism excited to be back in business, considering many people in southeast Alaska earn their income from out-of-state visitors. Cruise lines will offer the opportunity to extend cruises with land tours, which include accommodations, transportation and some meals.

While early May often carries a chill in the air, you might encounter temperatures in the 60s by the end of the month. The warmer weather means glaciers begin shedding ice more frequently, so you have a better chance of experiencing the sight and sound of a house-size chunk of ice calving into the sea. Another bonus is that Alaska's large mosquito population has yet to emerge.

Related: Alaska cruise guide: Best itineraries, planning tips and things to do

The cruise season beefs up in June, with the number of ships growing; the season is in full swing by the end of the month. The midnight sun means many hours of daylight — especially on June 20, the longest day of the year. You'll have to stay up late to see any darkness at all.

Early in June, the ships still mostly carry adults, with the family crowd — including multigenerational groups — arriving later in the month.

Shore excursion experiences abound. Temperatures are pleasant — in the 60s and sometimes higher, with wildflowers in bloom and glaciers calving. Anglers will find opportunities to reel in halibut along with king and sockeye salmon and rainbow trout. In addition to humpbacks, you might also spot belugas and seals with their pups as you sail.

At the beginning of the month, you might still be able to find some early-season pricing; the peak season for Alaska cruising begins in late June.

July and August

Summer is the height of the Alaska cruise season, which means crowds in port towns, especially when several ships are in port at the same time. You might have to wait hours for a table at the popular Tracy's King Crab Shack in Juneau.

It might surprise many, but July and especially August are rainy, so don't expect endless sunshine. That said, you are in Alaska at a time for festivals and other special events, and frontier towns really come alive.

Temperatures will be in the 60s, sometimes higher — you might even see 80s in Juneau in July. During long days of light, you'll find hearty Alaskans swimming in the sea and enjoying water sports. Shore excursion options will be in full swing.

During both months, you will encounter peak-season pricing. Unless you booked early, cabin choice could be limited — especially if you are looking for a fancy suite or cheap inside cabin; those tend to be the first categories to sell out. Balcony cabins are particularly popular in Alaska.

Mosquitos enjoy the summer, too, so pack bug spray. July and August are also spawning season for salmon, so you might spot grizzlies and brown bears near rivers and streams.

Keep an eye out for seabirds and songbirds, seals, Steller sea lions and humpback whales. Marine life is so prolific that some small-boat shore excursions guarantee you will see animals. Bears will be fishing; in late August, they will be looking for blueberries, which also become a featured item on restaurant menus. Toward the end of August, you'll see leaves changing to fall colors.

The beginning of September is much like August, but after the kids go back to school and the family crowd departs, it's shoulder season for cruising and pricing drops. Most cruise ships will have repositioned out of the state by the end of the month. You will experience a change of season, with cooler temperatures (in the 50s or lower) and some rain.

Mid-to-late September is one of the best times to spot wildlife in Alaska. I have had extraordinary experiences. Once, I watched a pod of humpback whales gather together in bubble-net feeding (corralling fish in a "net" of bubbles) to fill their bellies in preparation for their annual journey to warmer waters. Bears will be hunting for the last of the berries and salmon, and caribou, deer and moose will be mating.

You'll see colorful fall foliage but not mosquitos. National park facilities and some tourist businesses will switch to winter hours. September is also a great time to get deals on souvenirs, as merchants sell off this year's goods at the end of Alaska's tourist season.

On clear nights, you have a chance of spotting the northern lights — though they won't shine as brightly as they do in winter. Rather than stay up all night, see if your ship or pre- or post-cruise hotel has a sign-up sheet for people who want a wake-up call should the lights appear.

A limited number of cruises in October (predominantly on Norwegian Cruise Line ) make it possible for cruisers to experience a taste of Alaska in winter without sub-zero temperatures. You will want to bundle up; the average temperature in Juneau in October is 39 degrees. Days will be short — there are only about 10 hours of daylight. You are likely to experience rain and maybe snow.

Some attractions and shops will be closed for winter, though your cruise line will still operate a full roster of shore excursions. On the plus side, you will experience southeast Alaska towns as they are most of the year, sans tourist crowds. Sit in a bar and talk to the locals as they prepare for the long winter ahead. Cruise fares will be discounted.

When is the best time to see the northern lights in Alaska?

If one of your primary objectives during your Alaska sailing is to get a glimpse of the northern lights , consider a sailing in late August, September or October. The lights are typically strong in Alaska from late August to mid-April.

Your best bet for a sighting will be in Fairbanks — it's situated under the "aurora oval," an area known for a high frequency of northern lights displays. Fairbanks is a popular stop on cruisetours, itineraries that combine time sailing with overnight stays on land. For example, Holland America's nine-night Denali itinerary begins with an overnight stay in Fairbanks in early September.

Denali National Park and Anchorage can offer a glimpse of the northern lights — though not as frequently as Fairbanks since they are farther south. Both destinations are popular cruisetour stops. If you're cruising into or out of Seward or Whittier, you'll fly through Anchorage on one end of your trip. Consider an extra night or two there if you want to try and catch the aurora.

It's incredibly rare to see the northern lights from aboard your ship in the Inside Passage.

What is the cheapest month for an Alaska cruise?

As previously mentioned, April, May, September and October are good months for an Alaska cruise if you're hoping to score a deal . In addition to cheaper fares, early and late sailings of the season see fewer crowds.

Bottom line

What is the best month for an Alaska cruise? Alaska is a thrilling cruise destination no matter which month you sail. However, some months might be better for you, depending on your interests. Look to the early and late sailings of the season if you are a bargain seeker. Choose a May or June sailing for drier weather and fewer mosquitos. Summer is the best time to cruise to see abundant marine life and birds. September can be a great month to see wildlife.

The Best Time to Cruise Alaska for Wildlife, Northern Lights, and Fewer Crowds

The best time to cruise Alaska isn't obvious—until you're quietly sailing along its calm waters under a cloudless, late-spring sky. It was on one such day that someone on board spotted a whale breaching. And then again. And again. Within minutes it seemed everyone on board had gathered at the railings on deck to watch. The captain of the ship nimbly repositioned us, giving both the port and starboard sides prime viewing, at a safe and respectful distance from the animals. With binoculars, cameras, and phones at the ready, the passengers and crew aboard  UnCruise Adventures'  86-guest  S.S. Legacy  settled in for what turned out to be an hour-long private show by a juvenile humpback who had migrated from Hawaii to spend the summer in the nutrient-rich Alaskan waters.

This is but one of the incredible experiences that may be had when visiting Alaska in the “secret season”—springtime. Not only are the flowers and plant life awakening from their wintertime slumber, so is its wildlife. Though the state’s more temperate summer season has long attracted its largest numbers of visitors, an increasing number of in-the-know travelers are looking to spring as the best time to cruise to Alaska , when they can count on fewer crowds—and increased savings—without sacrificing their chance to take advantage of the state’s landscape and  wildlife sightings .

On that same late-April voyage with UnCruise, the  Northern Lights  danced through the sky on night one, and through the week we spotted grizzly bear mamas and their cubs skirting the coastline; bald eagles soaring overhead; humpback whales and orcas breaking the water’s surface to breathe; puffins, seals, and sea lions bobbing in the water and laying out on rocks—even a wolf on the shoreline, feasting on a fresh kill. (Our captain said he had seen a wolf in Alaska only twice in his 30-year career.)

We sailed roundtrip from Juneau, and while I’ve visited the capital city during the busy summer months, I found the restaurants, bars, and shops much less crowded, reliably filled with locals for the most part. On the water, we rarely passed any other ships or boats, aside from fishermen out for their catches.

According to  Travel Alaska , cruising is the most popular way to explore the state, and Cruise Lines International Association Alaska predicts that 1.64 million cruise line passengers will sail to and within Alaska in 2024.

But when is really the best time to sail Alaska? We’ve broken the seasons down for you, including the highlights of each, as well as the best cruise lines and cruise ships to consider so you can make your bucket list dreams come true.

Celebrity Cruises’ Celebrity Edge sets sail for the first time in Alaska this year.

April and May

If your schedule allows, not only does sailing Alaska in April and May afford the possibilities of glimpsing the Northern Lights and seeing wildlife emerge from their winter hibernation, it’s a more affordable and less crowded time to cruise, too. April and May are also the driest months in Alaska, so the chances of rain are slim.

Norwegian Cruise Line kicks off the 2024 Alaska cruise season when Norwegian Bliss sets sail on a weeklong, roundtrip itinerary from Seattle; she will be the only ship sailing in Alaska the first two weeks of spring. Balcony cabins are still available on the season’s inaugural sailing at a discounted fare of $1,029 per person .

Smaller ships like those that comprise UnCruise Adventures ’ and Alaska Dream Cruises ’ fleets can maneuver closer to the coastline for better views of bears rambling along the beaches and on-land excursions without another soul around. Uncruise’s 12-night “Inside Passage” itinerary departs April 15 with rates starting at $6,300 per person , and Alaska Dream Cruises’ seven-night “Last Frontier Adventure” has starting rates from $3,995 per person .

June to August

Warmer temperatures, an average of 17 hours of daylight, and schools’ summer vacations all make Alaska a popular destination for cruising in June, July, and August. Expect crowded ports and more ships out on the water, but that’s not to say it’s not a good time to set sail: bears are still active, as are whales and native bird life.

Holland America Line, which has sailed in Alaska for 75 years, offers 50 itineraries throughout June, July, and August, including the new 28-day Alaska Arctic Circle Solstice itinerary that departs June 9 from Seattle; verandah staterooms start at $7,259 per person . Family favorite Disney Cruise Line offers 13 itineraries over the summer, including a seven-night itinerary from $3,467 per person .

Not only is school back in session in September, which means fewer crowds at ports, but the chances of seeing the Northern Lights return, especially if combining your cruise with a land tour that takes you further north into Alaska. Fall is also mating season for wildlife, so expect to see some friskiness.

Celebrity Cruises’ Celebrity Edge sets sail for the first time in Alaska this year and has four six- and seven-night itineraries in September, starting at $599 per person . For a cruise-tour option, Princess ’ 12-day Denali Explorer itinerary blends five days on land with a weeklong cruise with mini-suite rates from $4,008 per person .

The Alaska cruise season winds down in October, with only a few ships setting sail. Just as in April and May, you’ll likely have the water to yourself, and even fewer people in the ports you call upon. Along with cooler weather, you’ll also find lower fares that will please your bank account.

Just as Norwegian Cruise Line kicks off the 2024 Alaska cruise season in April, it’s the last cruise line to set sail in the state, and the only one to sail in October. The seven- and nine-day itineraries sail roundtrip from Seattle, and a recent search found fares more than 80% off published fares, starting at $499 per person .

Alaska cruise in early May - Good idea?

By Geoffa30 , June 6, 2021 in Princess Cruises

Recommended Posts

We have never sailed to Alaska but are thinking of booking an Alaskan cruise in the next couple of years. We’re flying in from the U.K. so ideally would prefer a cruise of longer than seven days. I’ve spotted the one below in May 22 on the Sapphire Princess. Hoping any Alaska cruise connoisseurs might be able to comment on whether cruising in Alaska right at the beginning of May is a good idea. Also, what do people think of this itinerary? It’s also offered in mid-September 22 but on the Grand Princess. I understand that May and September are the shoulder months so less busy and cheaper but are they best avoided for weather etc.? All opinions welcome. Thank you.

In my view, early May is too early.  I would lean towards the late summer cruise in September when the weather is more likely to be welcoming.  I understand that’s all a matter of opinion and it’s easy enough to put on sweaters and jackets.  I suppose if you’re interested in views of mountains still covered in snow and that sort of thing... go early.  Coming from Ottawa, seeing a lot of snow and ice in early May is not something that particularly excites me.

I've been to Alaska twice, once the 1st week of May, and once the 2nd. The first cruise the weather was warm enough not to wear ajacket, the second one was cold and rainy. You can't figure Alasa weather. It changes rapidly.

I agree with previous poster, no way to judge.   I took a positioning cruise from California to Alaska, late April, early May, weather was awesome, luck of the draw.  We were 1st ship of the season, no other ships, it was great.  I bought short sleeved tees as I wasn't prepared for warmer than normal. 

I haven't been to Alaska in awhile, but I would do first cruises or last, never what is considered ideal time to cruise.   

Our first cruise to Alaska left about May 15.  Weather was warm and perfect.  No bugs.  We have been twice in Sept. and had some rain and cold weather.  However, we saw more wildlife in Sept including bears.  All three trips were great.  Your itinerary looks very nice to me.  You will love the trip

September has (historically) the most rain and potential bad storms of any of the cruising months to Alaska.

I have gone Mid-May many times and they have all been wonderful. I have never gone early May but would be willing to do so. I would pick early May over mid-September in a heart beat.

As far as cruising months, May has the least amount of rain and every month after has more potential for rain (historically).

Have gone to Alaska  twice in early May and loved it . My college  roommate's daughter  was a Park Ranger  in Denali  and recommend  going  then. There was snow cover in some areas, spectacular  waterfalls  due to melting snow, foliage  was just blooming and crowds of tourists  minimal . IMO a great time to go.

We did the first Alaska cruise of the season, early May, in 2015 and it was wonderful.  There was still ice and snow in many areas and it was breathtaking to see!  The weather was mild, but a couple of days were quite warm.....no jacket required.  We did an August sailing the following year and it was a bit disappointing.  Scenery was not as spectacular and lots of mosquitoes!  However, most people prefer the later sailings, so something for everyone.

We’ve been mid to late May twice, and it was nice. Still snow on the ground and lots of bear cubs with their mommas.

This isn't exactly your question, but this itinerary is nice because it includes Sitka, which the rest of Princess' itineraries don't include.  I've been to Alaska the last weekend in May and the weather was perfect with few crowds.

May is a great time for Alaska cruises.  Days are longer (for example, sunset in Juneau is around 9 pm in early May vs. 8 pm in late August).  There is more snow in the mountains in May, so the scenery is even more spectacular.  There are fewer bugs in May than there are later in the summer.

May is a bit cooler than later in the summer, but the difference is not huge.  On the other hand, there tends to be much less rain in May.   Rather than relying on anecdotal reports on the weather, if you look at the long-term averages based on National Weather Service data, you will see that in places like Juneau, Skagway, and Glacier Bay, there is half as much rain in May compared with August.

I worked on cruise ships many years ago, and did two full seasons in Alaska. I would pick May over September. Alaska’s weather is unpredictable but generally May is drier than September. Plus you will see more snow and ice whereas September is greener. We’ve cruised in May and didn’t even need jackets when we were at Columbia Glacier. 

Amazing itinerary, by the way. You’ve got me thinking now, lol. 

Thanks everyone for the responses so far. Certainly looks like May could be a good time to visit. We’re more swayed towards May because we’re familiar with Sapphire Princess.

Princess has started releasing 2023 itineraries recently. Any opinions on when Alaska 2023 might be released?

Wishing on a star

Okay...  I haven't read the other opinion and responses.

But, we cruised in late May, so here are my thoughts.

FIRST:  I just did some quick searches, and I don't think it is pulling up all of the sailings right?

I had looked at the Majestic sailings, and this time I didn't see them showing up.

So, make sure you search different ways to see all sailings.

When I put in just the month of May only... that seemed to be working.

When I selected several consecutive summer months, I don't think it was working.

May CAN be dryer, based on the weather averages.

But, on the coast, on a cruise ship, it can be rainy and cloudy and cool almost every day.

The coastline is a Maritime Rainforest climate.

The very beginning of May might be early, and I wonder about excursions...

Back when we cruised, a lot of things didn't begin until mid to late May???

So, you might want to double check.

We really enjoyed the pre-cruise smaller boat tour of Prince William Sound before boarding!

Once you go inland, like on excursions, that can be different.

The only sun we saw on our late May 7-day cruise was when we drove inland over the mountains to Canada to Carcross and Emerald Lake.  (it really was emerald)

Secondly, if this matters to you...  I would consider two consecutive 7 days, or the addition of the Land Tour, on a newer ship.  You would get most of the same ports.  On the NorthBound and Southbound Voyage of the Glaciers. (on Majestic?  with its nice covered solarium are which would be welcomed in Alaska in May!) ) you would get both Hubbard Glacier and Glacier Bay, two stops at some other ports....  At Juneau for example, you could go Whale Watching on one port day, and do something different on the second port day.

Look at each ship.

I was excited to see the Majestic move to Alaska. (if it remains there????) As it has the really nice covered Solarium.  Not sure if Sapphire has that or not?

Hope this helps!

We have done 8 Alaskan cruises and ALL were in May, never had any issues, horrid weather can hit Alaska ANY month of the year but the BEST thing about May is the snow melt is in full force so waterfalls and rivers run high and fast, the mosquito's are not out yet AND its less expensive to cruise in May, especially the 1st 1 or 2 cruises

2 hours ago, Wishing on a star said:     Look at each ship. I was excited to see the Majestic move to Alaska. (if it remains there????) As it has the really nice covered Solarium.  Not sure if Sapphire has that or not?   Hope this helps!

The Sapphire has the solarium. It is a great ship.

I have been to Alaska more than a dozen times in May and have received sunburns.  There can be sun in May in the ports and at the glaciers.

If there are cruise ships coming, there will be excursions.

You can also departure from San Francisco. Same basic stops but due to distance it is 10 days  (more sea days).  Check airfare.   Also, I consider May better because of few children as school is still in session.

Finally, Glacier Bay National Park is truly IMHO the main event. If you change cruise try to keep it on the itinerary.   

We are booked on the May 10 and May 20 cruises in the Ruby. 

Cruise Raider

We've cruised up to Alaska a dozen times (yes, it's our favorite itinerary).  So far, we've gone once in early May, once in mid-May, once in mid to late August, once in mid to late Sept and the rest in the first week of Sept.  

Our worst weather sailings (we still had a blast) were the ones in mid-May and the one in mid to late September.  

Our best weather ones have been in late August and early September.  The early May one we went on was actually surprisingly nice.  But one thing to keep in mind is that the very early season sailings are oftentimes precluded from getting up close to the glaciers due to ice in the water.  

Early Sept is my favorite time to go and we've always had great luck in terms of weather and if you are a shopper, there are so many deals to be had.  Don't forget to take your sunscreen and layers with one waterproof layer in the event of rain.

They will see far more Alaska with their itinerary. Less sea days but Alaska. If they are coming from UK - they probably want to see Alaska.

This. Go in September and you can see salmon run which is a bonus.

We love to cruise to Alaska in May for all of the reasons people have mentioned (weather, price, crowds, etc).  You will miss some things (such as salmon runs) but IMO it is worth it.

I think this itinerary is great!  We cruise (except for 2020...) two or three times a year to Alaska and I would pick this trip!  In fact, I sent it to my hubby to consider.

Your visits to these ports are long enough to do some truly wonderful excursions depending on your interests.  A great mixture of ports and glacier visits!  You get to visit ports that are usually not included in a 7-day cruise—Sitka, Prince Rupert.  I think this cruise will give you a great taste of southeastern Alaska.  

An Alaska cruise is not about the ship but the ports!  Enjoy your planning!

Agree with the May, yea sayers!  There is the possibility the ship may be unable to get up as close to the glaciers as the ice burgs that have already formed are not melting as fast, but it will still be wonderful. seals will be having babies on the ice flows that float by as well.  SOOOOOO glad you are doing the Vancouver departure. The trip on the east side of Vanvouver island is so much nicer than leaving from the USA and going up the west side of the island where you don’t even see the shore.  you are in for a wonderful treat of a trip. 

We have cruised Alaska 5 times, all in May or last week of August (we try to avoid the kids) While I have heard May can be variable we have always had good weather, even hot in Skagway once.  Ketchikan may be rainy (twice for us).  Bring layers, it is obviously cold viewing the glaciers.  Late August was wonderful for grizzly sitings on sunset tours.

Also glad you are doing the inside passage out of Vancouver, our favourite part of the cruise...we even forgo the dinner so we can enjoy the sailaway and most of the incredible scenery along the inside passage. Exceptional!

We will be back when this hideous disease is done.

Enjoy youselves.

I have traveled to Alaska in May, middle of summer, and late September.  Your itinerary is outstanding.  Especially if you are flying from the UK to Vancouver roundtrip.  I would spend a few days in Vancouver before getting on the Sapphire.  Good choice of ship.  

The only down side is that some of your Glacier days may be hampered by too much ice.  You may not be able to get too close to the glacier.  

The weather is lovely in May.

Glacier Bay usually doesn't have ice problems. Hubbard glacier and Tracy Arm can. Though I missed Hubbard in July - so one never knows. Going later doesn't guarantee glacier access.

The Best Time to Cruise Alaska

T he best time to cruise Alaska is in May or June, at the beginning of the cruise season. Alaska’s cruise season has always been short, peaking quickly at the height of the summer months and then done by early fall. But as the destination has grown in popularity, the season has extended, and there’s a definite sweet spot to target. In May and June, the days will be at their longest, the weather (although still unpredictable) will generally be its sunniest and driest, and the range of excursions and options at their most plentiful.

With that in mind, Alaska is still a dynamic destination—no one snapshot of time during the year is guaranteed to encompass all this state has to offer . There are always tradeoffs. Visit too early in the summer, and you'll miss the salmon runs (and the bears that come to feed on them); visit too late, and much of the wildlife that attracts summer visitors will have either started retreating for warmer climes or begun looking for a den to hibernate in for the winter.

Alaska’s weather is unpredictable, to say the least. There are days throughout the year when there can be a temperature swing of a hundred degrees on opposite ends of the state—50 degrees Fahrenheit in Sitka and 50 degrees below zero in Fairbanks , for example. May can be one of the finest months across Alaska, as daylight reaches near-summer heights, while June is even nicer, with the last chill of the arctic winter departing for the season.

The Official Visitors Guide for Juneau playfully uses a raindrop graphic for every month in the calendar (in Southeast Alaska it’s never a question of whether it will rain, but how much it will rain). Wetter weather often sets in during the month of July, getting progressively wetter going into autumn. Juneau averages 15 days of rain in June, reaching 21 days of rain by October. In Anchorage and the northern part of the state, the rain often turns to “termination dust”—i.e. snow—as early as late September.

The Alaska cruise season begins in mid-May, but it doesn’t reach full swing until after Memorial Day. Sailings departing earlier in the season will less frequently be sharing berth space in port with numerous other ships, meaning that crowds in the ports will be somewhat lighter. Later in June and through July, visitors will find themselves at the peak of the short season, when the maximum amount of cruise ships and land visitors all pour into small town centers and cycle through popular tourist attractions on a relentless schedule.

Tourist Attraction Availability

The maxim on Alaska cruises is that it’s best to book ahead to guarantee prime spots on shore excursions—although, with fewer travelers vying for slots in the shoulder seasons of May and September, that availability tends to sell out later. Wildlife tours, for example, popularly sell out of their early morning slots early, as this is an ideal time to see the wildlife before it gets exasperated with the streams of tourist buses and boats.

Offered by Princess Cruises and Holland America Line , fishing excursions that allow guests to have their catch prepared and served to them onboard the ship also sell quickly. Cruise goers set on this experience should check frequently with the cruise line regarding the anticipated permitted fishing season, as the catch is strictly limited or sometimes prohibited early on during the run, and the state’s regulations change frequently based on observed conditions.

When planning your cruise, the weather should be a consideration for many shore excursions. For example, flightseeing via fixed wing or helicopter is a popular way to see glacier fields and spectacular mountain vistas, but small aircraft are sensitive to weather conditions. Choosing to cruise during the dryer months of May and June can help give you a better chance at participating in these weather-dependent excursions, although of course there’s never a guarantee.

Alaska cruises are popular with multi-generational groups, and as such, North American school schedules tend to dictate pricing peaks. Price-conscious travelers will generally find price breaks before Memorial Day or after mid-August, when schools in many parts of the country will be in session.

Cruisers planning to sail from mid-June through mid-August should start looking at sailings up to a year in advance, particularly if there are stateroom or itinerary preferences (popular sailings that include stops in Glacier Bay or Icy Strait Point book quickly).

Another time to book is during the “Wave Season” during the first two months of the year, when cruise deals abound for all destinations. Alaska cruisers can also find good last-minute deals just a few months prior to summer departures, although the best availability for these deals is often during the May shoulder season, or for the last remaining staterooms or cruise tour slots for sporadic dates throughout the summer months. Last-minute deals are also most common on large-ship lines, including Cunard , Celebrity , Carnival , and Royal Caribbean .

Cruisers booking small-ship cruises like Uncruise Adventures or the Indigenous-owned Alaskan Dream Cruises should also plan to book far in advance, as the small capacity of the ships often limits availability on popular sailings.

The Best Time for Whale Watching

It depends on the species. Gray whales can be seen in Alaska waters as early as April. Orcas tend to migrate to (and concentrate in) Southeast Alaska in May and June, while humpback whales are at their peak in June and July. Beluga whales come later in the summer, following the salmon runs in Southcentral Alaska; the best place to see them is around Cook Inlet and the Gulf of Alaska from mid-July through August.

The Best Time for Viewing the Northern Lights

Generally considered a winter activity, the northern lights (or aurora borealis to be technical) are actually present in the upper atmosphere year-round—it’s just too light to notice them during the endless, sunny days of the Arctic summer. By August, it’s dark enough during the night to see the northern lights, and cruises in September afford the best chances with longer, darker nights—although it’s worth noting that September is one of Alaska’s rainiest months, so there’s more chance of cloud cover. That said, the routing of cruise ships away from shore and the light pollution of major cities affords some of the best conditions for northern lights spotting.

Key Events & Festivals

If you're extending your time in Alaska and planning a pre- or post-cruise itinerary, or you're simply looking for fun things to do at your ports of call, these are the top events and festivals to check out during peak Alaskan cruise season.

• In Anchorage, Summer Solstice is observed with a festival, which also coincides with Pride and Juneteenth, making the entire week feel like an endless parade. Visitors to Fairbanks—where the solstice day is a full 24 hours—will find a street festival and baseball game.
• Pride events can be found throughout Alaska in June, even in tiny Skagway, which has a year-round population of just 1,200.
• The Sitka Music Festival takes place through the month of June, with concerts and intimate chamber performances by visiting and local musicians.
• Every July 4 in Seward, competitors run a marathon, Alaska style—that is, up the side of the aptly named Mount Marathon . Throngs of crowds gather to watch and cheer on their favorites.
• Independence Day is observed throughout Alaska with fireworks and parades, most notably in Anchorage.
• Forest Fair is traditionally held in Girdwood, a progressive resort community south of Anchorage, the weekend after Independence Day.
• Off the cruise ship track (but worth a visit for visitors ending their trips in Anchorage with a day or two to spare), the Alaska State Fair is a supremely local gem, with famously gigantic vegetables, local arts and crafts, and a carnival midway that could be plucked right out of any all-American town.

Frequently asked Questions

What are the best months go on an Alaskan cruise?

May and June are the best months to go on an Alaskan cruise, as the weather will be at its warmest and driest, and you'll have the widest range of shore excursions available.

What is the best month to see whales on an Alaskan cruise?

You can spot whales from April through August, although the type of whale you'll see will greatly depend on the month. Gray whales, for instance, can be found in April, while orcas appear around Southeast Alaska in May and June. In June and July, you can watch humpback whales, while beluga whales pop up in Southcentral Alaska from mid-July to August.

What is the best time to see the northern lights on an Alaskan cruise?

The best time to see the northern lights is in August and September, as the nights get longer and darker heading into winter. However, keep in mind that September is a particularly rainy month, so there's a chance that it will be too cloudy to see them.

Alaska Cruise Weather by Month

Alaska Cruise Temperature by Month

Whether soaking up the golden sun on a fishing expedition or feeling the crisp breeze as you zipline through picturesque landscapes, you may notice that on an Alaska cruise , weather can vary greatly month-to-month. Princess cruise itineraries travel to the Southeast and Inside Passage regions of Alaska from May through September when wildlife is bustling, greenery is flourishing and salmon are running. Temperatures can reach anywhere from the low 30s to upper 80s depending on your month of travel as well as the port of call. We always recommend that you dress in layers to prepare for whatever weather comes your way. To help you get ready for your awe-inspiring adventure, learn about Alaska cruise temperatures by month.

Alaska Cruise Weather in May

After spending the winter in warmer climates, humpback whales migrate north and break the waters of the Inside Passage, marking the dawn of Alaska’s most vivacious season. Hundreds of king salmon grace the majestic waters of the Pacific while freckled lynx bask in the early summer sun. Thanks to the modest daytime temperatures and refreshing evening climates, May is peak season for many of Alaska’s most cherished wildlife. Weather typically ranges from the -1 to a high of around 12 degrees Celsius. May itineraries invite guests to pack jumpers and jackets for easy layering.

Alaska Cruise Weather in June

Feel the warm embrace of the summer sun throughout June when the Land of the Midnight Sun experiences the height of its daylight. With over 18 hours of golden sun each day, Alaska landscapes kiss the snowy surfaces goodbye and welcome the lush green meadows that bear the fruits of winter’s labor. With newly dried surfaces, hiking expeditions commence. As you venture into the depths of Alaska’s wilderness, reach new heights where you can enjoy unparalleled views of staggering glaciers and roaming hillside wildlife. With lows around 5 and highs around 18, allow the revitalising, crisp breeze to tickle your neck as you rejoice in the unforgettable climb.

Alaska Cruise Weather in July

As temperatures continue to rise, relish in the warmest month of the year when Alaska’s wildlife comes out to play. In Icy Strait Point, find regal brown grizzly bears roaming through streams in search of fresh salmon. Or, look for lively humpback whales making a splash off the coast of Juneau. As you embark on your summer adventure, bring light jackets for hiking through shady regions as well as plenty of sunscreen for basking in 18 hours of glorious sunlight each day this month.

Alaska Cruise Weather in August

Cast your line into the marvels of an Alaska summer by cruising in August. As you sail into each port of call, delight your taste buds in the delicacies of Alaska’s waters. Donning subtle notes of the sea, the silver salmon is one of the most sought-after fish and just so happens to be most fruitful this time of year. Whether or not fishing is your forte, be sure to pack water-resistant apparel for every splash and sprinkle that may arise from kayaking down crystalline fjords and hiking through misty rainforests. With lows around 5 and highs of around 18, you’ll feel refreshed and eager to explore the captivating wonders of Alaska.

Alaska Cruise Weather in September

As September begins, the sun dips below the horizon signifying the inauguration of autumn. The lush green forests transition into vibrant hues of gold and saffron while the mountaintops become freckled in snowfall. Daylight quietly recedes and the growing twilight perfectly contrasts the luminous green lights of the Aurora Borealis . The enchanting colours invite you to marvel at the miracles of Mother Nature that so often act as the inspiration for treasured postcards. With only 12 hours of sunlight, temperatures range from around 6 degrees to around 12 degrees. These new, cooler climates encourage Alaska’s famed wildlife to begin preparing for hibernation. Gaze at the water’s surface as thousands of bald eagles congregate to enjoy the final salmon of the season.

Best Month to Take an Alaska Cruise

What is the best weather for an Alaska cruise? Temperatures can vary anywhere between 30 to 80 degrees throughout the summer travel months – inviting guests to layer on the jumpers and windbreakers as weather can be unpredictable. So, the best month to travel to the Great Land depends on what you want to do. For the fishing aficionado, consider May when king salmon reach their greatest appearance. If you prefer to explore the lush scenery by foot, wait until June when the sun has overcome the frosty terrain of the Inside Passage and trails are primed for adventures. Regardless of which month you choose to explore Alaska, you’ll encounter iconic marine life and embark on heart-stirring adventures when you set sail with Princess.

Best Time to Visit Alaska: Month by Month Breakdown (2024)

Trying to decide the best time to visit Alaska? This month by month breakdown will help you figure out the best time to travel to Alaska, depending on what you’d like to do and see.

We spent 5 weeks exploring Alaska and can attest that is the last real wilderness left in the United States. It is an untouched, rugged, and pristine destination that’s just waiting to be explored by intrepid travelers. 

Be sure to also check out our extensive Alaska Travel Guide

The northernmost state though, is a very seasonal place to visit, because the vast landscapes and sporadic towns and small cities are at the mercy of the weather. 

This far north, you find a land of extremes. Alaska endures long, dark winters with some areas having no daylight for weeks at a time. There are fierce snowstorms and temperatures are well below zero for much of the year. 

Summer is beautiful, and arguably it’s the best time to visit Alaska because the days are long and the temperatures are relatively high. Although, I’ll admit that we prefer the spring months for better contrast and cooler weather.

You’ll even catch the midnight sun in some locations. But the summer season is short, lasting only from late May to September, and this is when it’s peak season, and the cities and glaciers are full of cruise ship tourists. 

So When Is The Best Time to Go to Alaska?

Table of Contents

When it comes down to it, the best time to plan a trip to Alaska depends on what you want to do in Alaska and which Alaskan destinations you want to visit.

If you want to go on an Alaska road trip , you’ll want to visit at a completely different time than if you want to see the Northern Lights . The Alaska cruise season is different still.

And while there are only a few months of the year where you can hike in the national parks, cities like Anchorage , Juneau , and Fairbanks offer a longer tourism season.

Below, we’ll go into a month-by-month breakdown of the best time to travel to Alaska. Once you know what you’d like to do, you can use this guide as a reference to decide the best time to plan your trip.

Best Time to Visit Alaska FAQs

Before we go into the month-by-month breakdown, here are a few quick answers if you’re wondering about things like the best month to see Northern Lights in Alaska or the best month to cruise Alaska.

April, May, and September are typically the cheapest months to visit Alaska. The weather isn’t perfect but it’s not winter and the crowds are a lot smaller. Just note that some activities may not yet be open (or may already be closing).

July tends to be the most expensive month to go to Alaska – because that’s when most people want to go to Alaska. It’s the peak of high season for both cruises and those flying in. Expect higher prices on accommodation, flights, cruises, and tours.

The Alaska cruise season runs from April to September, which peak months being June-August. While most would say that summer is the best time to cruise Alaska , I actually think that spring is an even better time!

The Northern Lights are technically visible from August to April. However, you’re most likely to see them between November and February.

The spring and summer months are the best time to see wildlife in Alaska. Grizzly bears are usually all awake from their winter hibernation in May. June is the peak season for whale watching and most other animals are active too.

Best Time to Visit Alaska: Month by Month Breakdown

To be able to plan the ultimate trip to the national parks, and to remote destinations, you’ll need to know the best time to visit Alaska.

Here’s our month by month guide on the weather and the best places to go! 

January in Alaska 

January is a cold, cold time to be in Alaska. But it’s also a unique time of the year to explore the state, as you’ll experience the region in the throes of winter. 

The far north of Alaska sees almost no daylight in January, being well within the Arctic Circle. However, stay south in Anchorage or Juneau and you can enjoy a few hours each day of sunlight.

In fact, the skies are beautifully clear when the sun is out for its brief stint each day. This makes January the best time to visit for flightseeing trips over the glaciers and mountains. 

At night you’ll likely see the Northern Lights too, especially if you head further north.

There’s ample opportunity for snow sports, including dog sledding and snowshoeing of course. You can learn more about local cultures during the dead winter months too.

Remember though that travel in January can be difficult, especially if you want to head to the Arctic areas.

Overland travel is almost non-existent, even in summer, and even less so in winter, of course. 

February in Alaska

In February, it’s just as cold and just as dark as in January, perhaps even colder depending on the weather patterns.

This is not the best time to visit Alaska, because there’s almost perpetual darkness and you’ll be at the mercy of the extreme weather. 

This is still very much winter. But as in January, stick to the cities and you can enjoy Alaskan culture at this unique time of the year.

You can still take the odd flightseeing trip if the skies stay clear and of course, this is a great time to see the Northern Lights. 

Head out from the cities and you’ll likely catch the Northern Lights in the sky, while there’s lots of chance to go dog sledding or snowshoeing too, all across Alaska. 

March in Alaska

While March sees the beginning of spring in more southern areas of the USA, in Alaska, it’s a completely different story. 

It’s still winter, but in March the temperatures are rising incrementally, and the darkest days are now over. 

The days are getting longer and this is a good time to visit if you want to enjoy outdoor activities in the snowy wilds of the Alaskan national parks. 

In fact, if you want to enjoy the Northern Lights, this can be the best time to visit Alaska, because you’ll catch them in the night, but still be able to enjoy the daylight hours too.

April in Alaska

April is when the weather begins to transition from winter to summer. This is the short Alaskan springtime and it’s the best time to visit Alaska before the summer crowds arrive. 

Small numbers of cruise ships begin to dock in places such as Anchorage or Juneau, while it’s much easier to travel overland. 

The wildlife begins to emerge from hibernation and if you head into the national parks you’ll begin to see all sorts of animals, including moose and perhaps even the odd bear. 

May in Alaska

May is the start of summer, or at least, the end of spring, and temperatures continue to rise all through the month. Truth be told, this is one of our favorite times to be in Alaska. There is still snow on the mountains, yet the land is green and flowers are starting to bloom.

In May, the days are now incredibly long, and the further north you travel the longer they’ll become. 

You’ll start to see whales in the ocean and more and more wildlife in the national parks.

In fact, this is probably the best time to visit Alaska if you want to spot wildlife because as the ice thaws across the state new life emerges into the sunlight.

Alaska is well and truly in bloom in May, and luckily, this is still very much a shoulder season too, because the summer crowds have yet to arrive in port. 

June in Alaska

Those summer crowds really make their first appearance in June, because this is the start of the high season. That said, we loved being there in early June. It’s not quite high season yet but everything is open and operating again.

This is not the best time to visit Alaska if you want the most popular places, such as Denali National Park or the famous glaciers around either Juneau or Anchorage, to yourself. 

Remember though, that Alaska is a vast place and there is so much more to see than just the tourist hot spots. We booked a trip to Bear Camp in Lake Clark National Park in the first week of June and were the first group to visit that year.

Take the time to head north, and you’ll quickly find the cruise crowds dissipate, and you’ll have the backcountry all to yourself.

Go to Fairbanks or head to the Kenai Peninsula, or better yet, head far, far north for the Midnight Sun in the Arctic Circle, where the sun never sets for most of the month of June. 

July in Alaska

July is still peak season and it’s still the height of summer in the state. If you’re looking to explore the national parks and to go hiking then this is the best time to visit Alaska. 

All the national parks are now well and truly open as the snow has melted in most locations, and you can enjoy trekking deep into Denali National Park or even attempt to summit Mount Denali if mountaineering is your pursuit of choice. 

The days are long and there is little darkness in July, and you’ll find wildlife everywhere, both in the oceans and on land.

For an off-the-beaten-track experience, take a cruise to the little-visited Aleutian Islands, which are glorious this time of the year.

August in Alaska

In August, the days begin to get slightly colder but there’s still a lot of daylight, with sunshine averaging around 18 hours per day across the state. The next time we visit Alaska, we want to go in August.

The wildlife is out and about and enjoying the weather before the short autumn soon arrives and before Alaska is then plunged into darkness when winter begins all too soon.

The last of the summer crowds are here in August, but by the end of the month, things are getting quieter.

This is a great last chance to enjoy the best of the national parks and outdoor activities in Alaska, while the waters off the coast will be teeming with humpback whales and orcas.

September in Alaska

As early as September the beautiful summer weather is gone, but it’s prefaced with a resplendent autumnal glow across the state. 

The wildlife is very active in September, and this is the best time to visit Alaska to see the wildlife preparing for their winter hibernation, by stocking up on food and hunting. 

You might have the chance to see the Northern Lights too, but you’ll need to head up north and get lucky.

The nights are getting longer but there’s still plenty of daylight too, and none of the summer crowds of the previous few months either.

October in Alaska

By October, winter is almost upon Alaska, and the days are getting much shorter and the nights are much longer. 

Wildlife begins to slow down in the wilderness and you’ll have a harder time spotting them in the wild as they prepare for the cold weather. 

This is very much a shoulder season meaning that there are few other tourists around.

Unfortunately, this is also a transition month and not just in terms of the weather but in terms of tourist activities too.

Many summer activities such as hiking are difficult now, while there’s also not much snowfall, meaning winter activities have yet to actually begin.

All of this ensures that October isn’t the first choice for many travelers and really isn’t the best time to visit Alaska. 

November in Alaska

November sees the beginning of winter and the start of heavy snowfall across the state. 

The days are much shorter now and temperatures are extremely low, especially at night time. 

You’ll have a great chance of seeing the Northern Lights however and winter activities will be in action, and you can enjoy snowshoeing and dog sledding. 

December in Alaska

December is a dark time to be in Alaska, but if you’re after a true winter escape and a guaranteed white Christmas, then this would make for an unusual getaway. 

Be prepared to be cold, but also be prepared for unique winter experiences. Stick to the south for better weather, and because you’ll have a high chance of seeing the Northern Lights too, rather than needing to venture too far north.

Best Alaska Cruise Outfits & Packing Advice

September 11, 2024

Alaska is one of the most popular cruise destinations . Passengers love the beautiful landscapes, the unspoiled nature, and the unique ports full of distinct character.

However, all passengers who have to go to Alaska for the first time have doubts about how to dress and what to pack for a cruise there .

Well, I must admit that packing for Alaska is not simple , but I will give you all the advice you need to avoid mistakes .

The Key to Alaska: Layering Like a Pro

The first thing I want to say, and perhaps the most important, is to dress in layers .

You should consider that the weather in Alaska changes very quickly , much more quickly than what we are used to in our cities.

It can go from sunshine to rain in the blink of an eye, so it’s crucial that you are able to adapt with ease .

Base Layer: Stay Warm and Dry

The base layer is the most important one. You should choose something that keeps you both warm and dry at the same time .

Alaska can be cold, but activities like walking, hiking, and sightseeing can make you sweat quickly.

For this reason, opt for fabrics that keep you dry like merino wool or moisture-wicking synthetics .

Middle Layer: Insulate Against the Cold

The middle layer is your insulation and should trap the body heat to keep you warm , especially during very cold days.

A fleece jacket or a lightweight down option is perfect for Alaska. Fleece is a great choice because it’s breathable and adds exceptional warmth without adding bulk.

Consider that you must also evaluate comfort ; avoid things that are too bulky and make it difficult for you to walk.

Outer Layer: Defend Against Wind and Rain

The outer layer is the one that comes into direct contact with the Alaskan weather so it absolutely must be waterproof and windproof (both are very frequent in this region).

I would choose a durable and good quality waterproof jacket . It will keep you dry but will also block out those sharp winds you’ll encounter on deck or during shore excursions.

Before you depart, check that it fits in your backpack so that you are comfortable in case the sun comes out and you want to take it off.

Daytime Outfits

Now let’s move on to some outfits you can wear during the day .

As we’ve already seen the most important thing to keep in mind is to dress in layers.

Even during the summer, between June and August, the temperature in Alaska can range from 47°F to 70°F , so you have to dress to be protected from the cold but still ready to remove some clothing in case it gets warmer.

Below you can see a very classic outfit with a hat, long-sleeve thermal turtleneck, and comfortable stretch pants.

As you can see it’s a perfect outfit for when it’s sunny and a little warmer .

Below here you can see a similar outfit but with the addition of a jacket in case it gets a little colder or for when it’s not sunny .

As I said before check that the material of the outermost layer is always water-proof in case it starts to rain .

As for style, many peoplel generally stick to the same warm and comfortable clothes for excursions.

In my opinion, the one aspect you can play with is the colors . For cruises in Alaska, I absolutely recommend earth tones like forest green , brown , and burgundy that complement the rugged, natural beauty of this region.

Oceania’s Riviera to Make Alaska Debut in 2025

• September 13, 2024

Oceania Cruises will debut the Riviera in Alaska in 2025, offering a series of itineraries from May through September.

Departing from Seattle, Vancouver, and Whittier, the voyages range from seven to 12 days and include ports like Homer, Sitka and Juneau. Travelers will experience Alaska’s culture and natural beauty through Native tribe visits, national park excursions and wildlife encounters. Each sailing will also feature an onboard naturalist providing expert insights into the region’s diverse wildlife, including whales, bears and seals.

“We’re thrilled to bring our 1,250-guest Riviera to Alaska for the very first time,” said Frank A. Del Rio, president of Oceania Cruises. “Our elegant, ultra-premium small-ship experience offers the perfect juxtaposition to Alaska’s outdoor adventures, and with Riviera being 30 to 50 percent smaller than other premium cruise lines sailing in the region, we’re able to bring our guests to lesser-known, more remote ports, for a true immersion into this fascinating destination.”

Guests can look forward to a variety of shore excursions, such as an Alaskan-style brunch in Juneau; an exclusive crabbing experience in Ketchikan; flightseeing over the Tongass National Forest; and a culinary adventure in Sitka.

Highlighted Alaska itineraries include:

• The eight-day Alaska Reflections, sailing from Vancouver to Whittier, visiting Ketchikan, Juneau, Skagway, Hoonah and Sitka. Departs May 13.
• The eight-day Explorer’s Alaska, sailing from Whittier to Vancouver, visiting Hoonah, Skagway, Sitka, Ketchikan and Prince Rupert. Departs May 21.
• The 12-day Wilds of Alaska, sailing from Vancouver to Whittier, visiting Klawock, Ketchikan, Wrangell, Hoonah, Haines, Juneau, Sitka, Kodiak and Homer. Departs May 29.
• The seven-day Alaskan Accolades, sailing from Whittier to Vancouver and visiting Hoonah, Haines, Juneau and Ketchikan. Departs June 10.
• The nine-day Majestic Alaska, sailing from Vancouver to Seattle and visiting Ketchikan, Juneau, Haines, Wrangell and Victoria. Departs June 17.

Oceania Cruises’ Alaska Explorer Youth Program will be available on all 2025 Alaska voyages, offering children ages 5-12 activities and events led by experienced counselors. Guests can also enhance their cruise with optional pre- or post-cruise land programs, such as the Discover Denali experience, which includes exploring Denali National Park and viewing North America’s highest peak.

Norwegian Cruise Line worker accused of stabbing 3 people onboard Alaska-bound vessel

The alleged incident happened west of vancouver island, british columbia, as the ship was sailing to alaska, by associated press • published may 7, 2024 • updated on may 7, 2024 at 10:04 pm.

A cruise ship worker from South Africa was arrested Tuesday in Alaska's capital city, accused of attacking a woman and two security guards with scissors on board the vessel, according to authorities.

The U.S. attorney's office says the man is charged with assault with a dangerous weapon within maritime and territorial jurisdiction. Online court records do not show an attorney for the 35-year-old man.

According to an affidavit from FBI Special Agent Matthew Judy, the man was recently hired by a cruise line and joined the ship, the Norwegian Encore, in Seattle on Sunday. The ship set off that day for a weeklong trip with scheduled stops in Alaska ports, including the capital of Juneau, and British Columbia.

The alleged incident happened west of Vancouver Island, British Columbia, as the ship was sailing to Alaska. According to the affidavit, during the 'late evening" Sunday, ship personnel saw the man trying to deploy a lifeboat, and he was taken by security to a medical center for an evaluation.

While there, he “became irrational and attempted to leave,” and “physically attacked” a guard and a nurse, the affidavit states. He ran into another room, where he grabbed a pair of scissors and stabbed a woman who was being examined, as well as two guards who tried to intervene before being subdued and held in a “shipboard jail,” the affidavit says. None of the injuries were considered life-threatening.

The ship arrived in Juneau on Tuesday, when he was arrested by the FBI, the U.S. attorney's office says.
