Bundle up and plan for extreme cold, limited daylight and sudden storms. Alaska winter weather demands serious preparation — the live forecast above shows current conditions, but typical winter spans October through April, with interior temperatures often dropping below -40°C and polar night enveloping the far north.
What is typical Alaska winter weather?
Winter in Alaska means persistent cold, heavy snowfall along the southern coast, and fierce winds in the Bering Sea region. In Fairbanks and the interior, highs in January average -18°C to -23°C, while lows routinely reach -35°C to -40°C. How cold does it get in Alaska? The official record is -62°C in Prospect Creek (1971). Along the Gulf of Alaska, Anchorage sees milder winter highs near -5°C but receives more than 180 centimetres of snow. Daylight shrinks to under four hours in northern Utqiaġvik, while Southeast Alaska near Juneau gets more moderate, wet maritime conditions.
When does winter start and end in Alaska?
Winter’s arrival varies by latitude. In the interior it begins in earnest by early October and lasts into early May. The northern slope sees snow linger through May, while the southern coast often gets a later start. This long cold season means how long is summer in Alaska is a common question – summer is brief, roughly June through August, with alaska weather in august bringing the warmest temps (low teens in the interior, mid-teens in Anchorage).

How cold does it get in Alaska?
Temperatures in interior Alaska routinely fall below -40°C at least once each winter. The lowest recorded temperature in the state is -62°C, and wind chills can push the perceived temperature well below -50°C during strong Arctic outbreaks.
Is the Alaska winter weather forecast reliable for travel?
Short-range forecasts (1–3 days) from the National Weather Service are quite accurate for populated areas, but Alaska’s vast size and complex terrain make extended predictions uncertain. Always check the live forecast above and local aviation/road advisories.
How long is winter in Alaska compared to summer?
Winter typically lasts 7–8 months north of the Alaska Range, while summer is only 2–3 months (June–August). In south-coastal regions like Anchorage, winter is closer to 5 months, with a 4-month summer window.
