Climate and Weather in Alaska

The state of Alaska, a Northern American territory that shares its borders with the Yukon Territory and British Columbia in western Canada, is characterized by its cold climate. The Alaskan climate comes in several variants, depending on the geographical position of the localities. Thus, the south coast of Alaska is influenced by a subpolar oceanic climate, resulting in less cold temperatures and relatively high rainfall in comparison to the rest of the territory, which is also the climate found in Anchorage. Inland, the continental influence primes the rest of the territory, which explains the difference in temperatures between the winter and summer seasons. The northern part of Alaska is used to a polar type climate.

The Spring Climate in Alaska

Spring is very short. On the south coast like in Anchorage, the spring season which starts in mid April and ends in May, is a grand opportunity to see the weather conditions improve; this is also the period when the melting snow causes the formation of wetlands. Walk with caution, if you are planning on taking a few hikes.

The Summer Climate in Alaska

June, July and August are the hottest months of the year. In Hawaii, this signifies the famous time for fun in the sun and beautiful bright days however in Alaska, wearing comfortably warm clothing is still a necessity. The only real advantage is that the sunshine lasts longer. Furthermore, if ever one were to find themselves close to the Arctic Circle, they will also have the chance to see the midnight sun.

The Autumn Climate in Alaska

Autumn starts in September and ends around the month of October in the south and begins in late August in the north. This season depicts deteriorating weather in Alaska; in just a few weeks, the maximum temperatures range between 17° C and 7° C.

The Winter Climate in Alaska

The cold that characterizes the winter in Alaska is far harsher than that of Utah, even if the Utah State of the northern United States of America is known for the harshness of the winter. Overall, warm clothes are simply a must for anyone wishing to experience a unique adventure in Alaska.
