We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: 1 are based on computer models that may have model-based errors, 2 are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and 3 have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.

Where to begin? June was the second warmest on record for Alaska. The hot temperatures were accompanied by dry conditions, creating the perfect set-up for wildfires. Alaskan wildfires have burned well 1. Nearly 1,, acres have burned just since July 3. Numerous large fires billowed smoke across Alaska on July 8, Both Fairbanks, in central Alaska, and Anchorage, on the southern coast, were under the pall, creating unhealthy air quality.
The smoke from those wildfires has drifted towards the major population centers and choked the air across southern western and interior Alaska, leading to the first ever dense smoke advisory for Anchorage and some of the worst air quality in the world in Anchorage and Fairbanks.
The smoke has made it difficult for the many people to cool off: air conditioning is rare, and opening the windows is a nonstarter. Meanwhile, the well above average air temperatures have also coincided with, and were likely influenced by, well above average ocean temperatures around the state as well as record-low sea ice in the Bering and Chukchi seas.
Overall, the total amount of sea ice in the Arctic is currently running neck and neck with , the year which ended up with the lowest ice extent in the satellite record. These drastic changes to the environment in Alaska, tied to human-caused climate change, have cascading effects throughout the Arctic. The lack of sea ice can lead to increased storm surges, coastal flooding and erosion. The changing shorelines have already forced some communities to relocate.
Warm summers and ice-free seas can negatively impact marine mammals, fish, and crabs. For example, warm summers negatively impact the survival rates of young fish species like walleye pollock. The fish prefer a large summer cold pool of water at the bottom of the Bering Sea.
Wind speeds are frequently above 50 miles per hour along the coast and in the mountain ranges. The tundra is at its best in winter for transporting heavy equipment on the frozen rivers and lakes. The precipitation is short of 3" The short days with dark skies and 3 hours of sunlight provide a unique experience of the fantastic Aurora or the Northern Lights.
It is necessary to have clothing suitable for extreme colds such as long thermal underwear, a winter jacket, parka with insulated hood, boots, and mittens. Alaska is a winter wonderland, but January weather is not for the faint heart. The days are short, and the daily sunshine lasts for 4 to 5 hours in the majority of the state. Snowstorms often stall everyday life with vast deposits of snow and raging winds that make it difficult for snowplows and trucks to operate.
February receives on an average 45" mm of snow, but the regions of heavy snowfall have relatively mild temperatures. The southern parts of the state are warmer than the north, with cheaper accommodation rates in the winter. Dog mushing is extremely popular, and winter is the time for sled dog races on the frozen rivers such as the Yukon and Chena. Ice fishing and ice skating attract plenty of interest.
Extreme winter clothing is mandatory in Alaska in February. March sees the transition from the winter to the spring season in Alaska with cold temperatures and a significant increase in daily sunshine hours. The mountainous area of Mount McKinley accumulates vast amounts of snow and maintains a permanent snowline. March registers an average of 32" Glaciers form a significant source of fresh water in the state. Late March is the usual date of arrival of the spring season, which awakens flora and fauna of the land.
Hibernating animals slowly rise from their winter slumber to feed upon the replenished stores of fresh food. Hunting, fishing, and wildlife watching are few of the popular attractions in Alaska that gain traction in March.
April is the driest month of the year in Alaska as the spring season brings increased sunshine to the state. The days are mild to warm, but the nights are often cold and below freezing. The snowfall is ample and averages 28" Sunglasses are useful while traveling over the snow during the daytime. Vast glaciers, roaring freshwater streams, beautiful lakes, and the call of the wild are irresistible.
Early spring is the time when grizzlies are busy fishing for salmons after awakening from hibernation. Expect black ice, numerous snowplows, and mush on the slippery roads in April in Alaska.
May is a beautiful month at the peak of the spring season in Alaska. Wildflowers bloom over the landscape, and wild animals roam the land. Spring offers an Alaska experience that is complete with the watching of the whales, bears, moose, and eagles in their natural habitat.
The precipitation is at a low 2. Skiing and sledding are still in full swing in the mountainous areas of the interior. Heavy jackets are avoidable during the day, but cold nights demand layered clothing. May is the last month of the snow season in Alaska except for the extreme north region.
June welcomes the warm summer season to Alaska with moderate to hot days and a decline in precipitation. Wildlife photography is at its best in the summer when the skies are clear, and the precipitation is at the lowest of the year. Snowfall is absent in the south, and the mild ocean temperatures are suitable for sea excursions. The bright weather is ideal for canoeing, kayaking, and watching marine life in the water.
June is a perfect time for hunting, fishing, biking, and hiking the nature trails in the state or visiting the state parks and wildlife reserves. T-shirts are ideal for hot days, while a light sweater or jacket is suitable for June evenings in Alaska. The evening sunlight stretches past midnight in Nome, just south of the Arctic Circle.
