Alaska – Best time to go

Best time to visit Alaska

With long days and nature in full bloom, the summer months are the best time to visit the expansive state of Alaska. Most tours operate from May through September and peak travel months are mid-June through August, so if you are looking for value, travel early in the season. 

Best times to visit

Alaska's weather and daylight varies wildly by region due to the large expanse of the state, so be prepared and pack for the activities you are planning. Short-sleeves for summer and down jackets in winter, but layers are key.

Daylight

During the summer months, Alaska can be almost fully light in the far north 23 hours a day, with daylight hours around 15 to 18 hours in other regions and June 21st is the longest day of the year.

Rainfall

May is dry with only 25% chance of rain, however August increases to around 50%. Again rainfall varies by region and the Southwest and Inside Passage can expect more rainfall than central areas and the Far North. But in general, Alaska has lighter rainfall than other areas in the United States.

Temperatures

Summer daytime temperatures range from 12°C to 21°C with highs into the late twenties, but with the long hours of direct sunlight it will feel slightly warmer. Always be prepared and pack layers.
