Alaska in May is the state’s best kept secret. The summer crowds haven’t arrived yet, prices are lower, and the landscape is doing something extraordinary — shaking off winter and coming back to life. Bears are emerging from dens, migratory birds are returning, and the days are getting noticeably longer. It’s not peak summer, but for the right traveler, that’s exactly the point.
We’ve spent many May months working across Alaska for National Geographic, Discovery, Disney, and Animal Planet on shows like the “Deadliest Catch“, “Life Below Zero“, “Bering Sea Gold” and many more.

My Experience with Alaska in May
The last time I was in Alaska in May I filmed a honey bee harvest, a shed build, and a bear hunt. The longer warmer days give way to a new landscape and new opportunities that the cold short winter days won’t allow. The ground is usually thawed enough to dig and install foundations, the wildlife is awake and active, and everyones attitude is much better!
After sleeping in arctic ovens and enduring winter storms that pound us with feet of snow, longer warmer May days in Alaska are enthusiastically welcomed. And while there are still challenges that come with working in Alaska in May, they are’t as stifling as the winter months. Mud season and mosquitos can make things difficult, but nothing a good pair of boots and a face net can’t mitigate.
I do admit that my considerations probably aren’t that same a casual tourists, and my bias towards weather may be skewed towards thinking 40 degrees is warm. I’ll lay out all the facts in the following article and let you decide. But all in all, after working many May months in Alaska, I would certainly recommend visiting the last frontier during this time.
Reasons to Visit Alaska in May
The Last Frontier is epic and awe in springing during every month of the year. So let’s break down the distinguishing factors on why visiting Alaska in May, is a good idea.
Witnessing the Return of Wildlife
May is the prime time to see wildlife emerging from hibernation and beginning to live their best life. Both black bears and brown bears emerge from their dens in the spring. By May, they’re actively foraging for food after a long winter sleep. Dall sheep and mountain goats are more visible in May as they move to higher elevations with the melting snow.
In addition to the larger mammals, spring brings a surge of migratory birds returning to Alaska. Keep an eye out for shorebirds and waterfowl. Sea lions and harbor seals are also active in May, hauling out on beaches and rocks to rest and pup.
While late June to August is considered prime humpback whale viewing in Alaska, they may start arriving as early as May. And places in southeast Alaska have year round resident Humpback whales, so there’s always a chance to see these magnificent creatures.
Longer warmer Days
Visiting Alaska in May offers a delightful taste of spring. The state begins to shed its winter coat as the days grow longer and warmer. Alaska temperatures in May range from the 40s to 50s, making it comfortable for outdoor activities. It might not be beach lounging temps, but its great hiking weather!
While it’s not quite summer yet, May still boasts significantly more daylight compared to other months. Most areas of the state will see an average of 16 to 17 hours of daylight in May. It’s kind of the perfect balance, plenty of daylight hours for adventures, but enough darkness to enable you to sleep. If you’re a light sleeper and visit in June, you might find yourself tin foiling your windows!
Shoulder Season Prices & Crowds
Compared to the peak summer months, May offers a chance to experience Alaska on a budget and with far fewer crowds. Flights and accommodations are usually slightly less expensive, making it a more accessible option for budget conscious travelers.
May Weather in Alaska
May in Alaska presents a fascinating weather tapestry, with conditions varying greatly across different regions. The first half of May in Alaska can still be a bit chilly and barren, but the second half starts to really heat up and feel like summer. Here’s a breakdown to help you plan your Alaskan adventure:
Southeast Alaska (Ketchikan, Juneau)
- Temperature: Expect cool but comfortable days with highs ranging from the mid 40s to 60s by the end of the month. Nights can dip down to the 30s.
- Precipitation: May is one of the drier months in Southeast Alaska, with an average of 7 rainy days. However, most of the region is rainforest, so showers can certainly still occur.
Anchorage
- Temperature: Highs usually hang in the high 40’s and low 50’s but can reach the 60s, with lows dropping to the mid-30s.
- Precipitation: Similar to the southeast, May weather in Anchorage sees less rain with an average of 7 days. Prepare for potential snow showers in the mountains.
Denali National Park & Fairbanks
- Temperature: May is on the cusp of spring in Denali and Fairbanks. Expect chilly days with highs in the low 50s Fahrenheit and lows dipping down to the freezing mark or even below.
- Precipitation: May can be a bit wetter in interior Alaska compared to the south, with an average of 8-10 rainy or snowy days.
May is Mud Season in Alaska
April and May in Alaska is “breakup season.” And no it isn’t what you’re thinking. Break-up season in Alaska isn’t when couples emerge from their winter slumbers and part ways in search of a fresh set of genitals. Although that probably does happen.
Breakup season occurs when the Alaskan permafrost, the permanently frozen ground, begins to thaw from the top down. This melting process creates a layer of mud on top of the still-frozen soil, making for a sometimes treacherous landscape. The severity of breakup season varies by location, with lower elevations experiencing the most dramatic transformations.
While Alaska’s mud season in May might transform some hiking trails into muddy bogs there is an upside. The snow melt and mud signifies Alaska’s rejuvenation. Witnessing the landscape awaken from its winter slumber, with wildflowers pushing through and wildlife digging in the soft earth, it can make a good trip great! So pack some buy some Xtratuf’s and embrace the mud!
May Festivals & Events in Alaska 2024
May in Alaska is when everyone starts shaking off their sleepy winter time attitude and starts gearing up for the busy summer season. It’s still relatively slow compared to June, July, and August, but there are some great events held in the month of May in Alaska. Here’s a list of some unique and unmissable Alaska events in May, 2024:
Great Alaska Aviation Gathering (May 4-5, 2024)
Held in Palmer at the Alaska State Fairgrounds and Palmer Municipal Airport, this free event is the largest aviation gathering in the nation. It features over 275 aviation exhibitors showcasing the latest technology, aircraft static displays, educational seminars, and live demonstrations. It’s a must-attend for pilots, aviation enthusiasts, and anyone fascinated by the world of flight. Check out there website for more details.
Kodiak Crab Festival (May 23-27, 2024)
The Kodiak Crab Festival is a week long celebration, traditionally held in late May around Memorial Day weekend. First held in 1958, the famous event celebrates the beginning of summer season and the communities bountiful seas. The five day May affair takes place….drum roll please….. in Alaska on Kodiak Island, obviously.
The crusty carnival has something for everyone. There’s a Saturday morning parade, coast guard demonstrations, a survival suit race, a fish toss, and art shows. And of course, the festival features a variety of food vendors serving up all sorts of crab dishes, as well as other seafood favorites. For more information check out there website.
Kachemak Bay Shorebird Festival (May 8-12, 2024)
Head to Homer for the Kachemak Bay Shorebird Festival, a birdwatcher’s paradise. May is prime time for bird migration, and this festival offers guided birding tours, educational programs, and family-friendly activities along the stunning Kachemak Bay. This years keynote speaker is Ted Floyd, the longtime Editor of Birding magazine.
Little Norway Festival (Third full weekend in May):
Held in Petersburg, this festival celebrates the town’s Norwegian heritage by honoring Norwegian Constitution Day on May 17th. The festival features traditional Norwegian food, music, dancing, and a badass parade down the towns main strip.
Iditarod Finishes in Nome
The famous Iditarod Trail Sled Dog Race starts in Anchorage in early March, but the winner typically crosses the finish line in Nome in mid-to-late March. However the final mushers — the ones completing the full 1,000-mile journey at their own pace — often don’t arrive until early May. Nome throws a party for every single finisher regardless of when they arrive, and watching the last mushers come in is genuinely one of the most uniquely Alaskan experiences you can have.
If you time your Nome visit right in early May you might catch a finisher coming down Front Street with their dog team — exhausted, frost-covered, and absolutely triumphant. It’s the kind of thing that reminds you why Alaska is different from everywhere else.
May Openings in Alaska: Tours & Parks
Alaska awakens in May, and so does its tourism industry! Many tour operators and outfitters across the state typically kick off their seasons around mid-May. This coincides with the arrival of longer days, milder temperatures, and receding snow, making it ideal weather for exploring.
So, whether you’re craving a glacier hike, a white water rafting adventure, or a wildlife viewing expedition, it all becomes available in mid May. In addition to that, some National Parks become much more accessible.
Alaska Railroad
The Alaska Railroad launches its summer service schedule in May, connecting Anchorage to Seward, Whittier, and Denali. It’s one of the most scenic train rides in North America and a great way to see the state without driving. The Coastal Classic between Anchorage and Seward runs through some extraordinary terrain and is worth building your trip around.
Denali National Park
Limited vehicle access on the Park Road typically begins in mid-May, subject to weather conditions. This allows you to drive a portion of the road and access some lower elevation trails. Full access to the park road, reaching higher elevations, usually occurs by early June.
We have some guides on Denali activities: Cycling Alaska: Denali, Anchorage, Fairbanks & More! (Trail Lists) and Denali Helicopter Tours: an Eagle’s Eye View of Denali National Park
Kenai Fjords National Park
Boat tours into Kenai Fjords National Park out of Seward start running in May — one of the most spectacular ways to experience Alaska’s coastline, glaciers, and marine wildlife. Humpback whales, orcas, sea lions, and puffins are all active in May. It’s one of the best kept secrets of shoulder season — full wildlife activity without the summer crowds.
Fishing Charters
Some of Alaska’s best fishing charter operators start their seasons in May. Homer halibut charters open for the season and king salmon begin running on the Kenai Peninsula. If fishing is your primary reason for visiting, May gets you on the water before peak season prices kick in.
White Water Rafting
Alaska’s rivers are swollen with snowmelt in May, which means higher water and more exciting rapids. The Nenana River near Denali and Six Mile Creek near Hope are both running in May. Check out our complete Alaska rafting guide for operators and locations.
McCarthy & Wrangell St. Elias National Park
The McCarthy Road is a challenging gravel route, so four-wheel drive vehicles with high clearance are essential, especially early in the season. I’ve driven the road in snowy, muddy conditions, and its always open, but it gets much easier and safer towards the end of May.
Once you get to the end of the road and finally reach the Park, the small town of McCarthy is there and by mid May the restaurants and lodging options are open and ready to cater to tourists. If you arrive before mid may, you better bring your own food!

How to Pack for Alaska in May
May is Alaska’s most unpredictable month to pack for — you might have sunshine and 60°F one day and snow flurries the next. The key is layers and waterproofing. Here’s what actually works:
Base Layers Merino wool over cotton every time. May in Alaska means cold mornings, warmer afternoons, and the possibility of getting wet in any of them. Merino regulates temperature, wicks moisture, and stays warm even damp.
- 🧣 Minus 33 Merino Wool Base Layer — worth every penny
Mid Layer A fleece or light down jacket for layering. You’ll be adding and shedding layers constantly in May — a packable mid layer that stuffs into its own pocket is ideal.
Waterproof Jacket Non-negotiable in May. Southeast Alaska averages 7 rainy days but showers can happen anywhere in the state. A proper hardshell over your layers keeps you functional regardless of what the sky decides to do.
- 🧥 Columbia Watertight II Jacket — reliable, packable, reasonably priced
Footwear May is breakup season — mud is everywhere, trails are wet, and unpaved roads are soft. Xtratufs are the Alaska standard for a reason. If you’re hiking serious trails add a pair of waterproof hiking boots. Thin wool socks for both.
- 🥾 Xtratuf 12″ Legacy Boot — essential for breakup season
- 🥾 Merrell Moab 3 Waterproof Hiking Boot — solid all-around trail boot
Bug Spray Early May is manageable but by late May mosquitos are emerging, especially inland. Don’t get caught without it.
- 🦟 Ben’s Wipes — easy to carry, effective
Sunscreen 16–18 hours of daylight means extended sun exposure even in May. People consistently underestimate this. SPF 50 minimum.
Gloves & Hat Still genuinely useful in May, especially early in the month and at elevation. A lightweight liner glove packs small and earns its place.

Alaska in May: The Cons
While May offers a glimpse of Alaska awakening from winter with longer daylight hours and returning wildlife, there are some downsides to consider before booking your trip:
Mosquitos
Mosquitos are no joke in May. Depending on where you are going they can swarm you by the hundreds.
Unpredictable Weather
May falls in the shoulder season, so the weather can be quite fickle. Expect a mix of sunshine, rain showers, and even the possibility of lingering snow, especially at higher elevations.
Limited Services and Amenities
Many tourist businesses and attractions operate on a summer schedule, and might not be fully operational until mid May.
Mud Season
Melting snow can create muddy conditions on trails, making hiking and exploring less enjoyable. Be prepared for muddy terrain, especially in areas with lower elevations.
Alaska in May FAQs
Is May a good time to visit Alaska?
Yes — especially if you want to avoid peak season crowds and prices. May offers longer days, awakening wildlife, and a raw, transitional beauty that summer visitors never see. The tradeoff is unpredictable weather, mud season, and some limited services early in the month.
What is the weather like in Alaska in May?
Variable and transitional. Southeast Alaska sees highs in the mid 40s to 60s with about 7 rainy days. Anchorage runs high 40s to low 60s. Interior Alaska and Denali can still see freezing temperatures and snow early in the month. Pack layers for everything.
How many hours of daylight does Alaska get in May?
Most of Alaska gets 16–18 hours of daylight in May, increasing toward the solstice. It’s significantly brighter than winter but not yet the near-24-hour daylight of June and July. A sleep mask is still worth packing toward the end of the month.
Can you see the northern lights in Alaska in May?
Unlikely — by May the nights are too bright for good aurora viewing in most of Alaska. If northern lights are your priority, visit between September and March.
What is breakup season in Alaska?
Breakup season is when Alaska’s permafrost begins to thaw from the top down, creating a layer of mud on top of still-frozen ground. It typically peaks in April and May, turning trails into muddy bogs and unpaved roads into challenging terrain. Xtratufs are essential. It sounds unpleasant but there’s a genuine beauty to watching the landscape come back to life.
Is May good for wildlife viewing in Alaska?
Excellent — May is one of the best months for wildlife. Bears emerge from dens in spring and are actively foraging by May. Migratory birds return in huge numbers. Sea lions and harbor seals are hauling out and pupping. Humpback whales may start arriving in Southeast Alaska. The wildlife is active and the crowds aren’t there yet — that’s a great combination.
Are national parks open in May in Alaska?
Partially. Denali National Park begins limited vehicle access on the Park Road in mid-May, with full access by early June. McCarthy and Wrangell-St. Elias become more accessible toward the end of May as the McCarthy Road conditions improve. Most tour operators start their seasons around mid-May.
Is May cheaper than summer in Alaska?
Yes — flights, accommodation, and tours are noticeably cheaper in May than June, July, and August. If you’re flexible on timing and want the Alaska experience without peak season prices, May is the best value month of the summer season.
What should I pack for Alaska in May?
Merino wool base layers, a waterproof jacket, fleece mid layer, Xtratufs for the mud, bug spray for late May, and sunscreen. Check our full Alaska packing guide for the complete list.
How are the mosquitos in Alaska in May?
Early May is generally manageable. By late May they’re starting to emerge, particularly in interior and wetland areas. Nowhere near as bad as July but worth bringing bug spray especially if you’re heading inland.
