For the second day in a row, the Juneau Airport has set a new record low temperature, this time for December 20.
According to official weather data, temperatures at the airport dropped to 7 degrees below zero Fahrenheit, breaking the previous December 20 record by two degrees. The reading marks another notable cold-weather milestone for the capital city, where such extreme lows are relatively uncommon.
Temperatures later rebounded slightly as conditions changed. By Saturday night, readings climbed back above zero, reaching the teens in downtown Juneau and at the airport. Meteorologists attributed the improvement to increased winds, which helped mix warmer air from higher elevations down to the surface.
Despite the modest warm-up, colder conditions persist in parts of the region. The Mendenhall Valley remained below zero, though temperatures there were reported to be warmer than Friday night’s lows.
The National Weather Service Juneau expects cold weather to continue into early next week, with residents advised to dress warmly and take precautions when heading outdoors.

While Southeast Alaska is no stranger to winter weather, back-to-back record lows highlight how sharply temperatures can drop during periods of clear skies, light winds, and Arctic air influence.
Residents are encouraged to monitor forecasts and local advisories as the cold pattern remains in place.
