Alaska Winter Climate Regional Differences Overview
Fairbanks and the interior valleys experience the most extreme temperature fluctuations, with summer highs reaching 80 degrees giving way to winter lows of negative 40 degrees. The state experiences long stretches of darkness, particularly in the interior and northern regions, where the sun barely creeps above the horizon for weeks.
In Fairbanks, temperatures of negative 20 degrees Fahrenheit are common, but when the wind picks up, the wind chill can plunge the perceived temperature to negative 50 degrees. Here, winter temperatures are relatively mild, with averages hovering around 20 degrees Fahrenheit.
