Check the live forecast above for current conditions, then plan for extremes: Alaska’s weather swings from bitter winter cold to mild, rainy summers, so pack for the season and expect sudden shifts.
What is the weather in Alaska like year round?
Alaska weather year round is defined by latitude and ocean currents. Winters are long and dark, with temperatures often below –20°C in the interior (think Fairbanks weather averages). Summers are short and cool, with coastal areas like Anchorage seeing 10–15°C and frequent rain. Daylight changes dramatically—endless summer sun, then near-total winter darkness above the Arctic Circle.
How do I prepare for a trip to Alaska?
Layered clothing is essential. In winter, bring a heavy parka, insulated boots, and thermal base layers. For summer, a waterproof jacket and warm mid-layer cover the rain and cool breezes. Check alaska weather by month before you go: May and September are transitional, while July is warmest but wettest. For a shorter outlook, look up weather in alaska 10 days from the live forecast above, or use alaska weather 14 days for a longer view.
Does it snow in Alaska during summer?
Yes, in mountainous and far-north regions. Snow can fall even in July on Denali or the Brooks Range, though it rarely lasts long below 1,500 metres. Coastal cities very rarely see summer snow.
What is the best month to visit Alaska?
For mild weather and long days, late June to early August is best. July offers the highest temperatures, but also peak rain. May and September are quieter, cooler and less crowded, with reasonable daylight.
How cold does Alaska get in Celsius?
In interior Alaska, winter temperatures commonly drop to –30°C to –40°C at night. Fairbanks has recorded –51°C. The all‑time low is –62°C at Fort Yukon. Coastal areas are milder, rarely below –20°C.
