Anchorage - Recent December Temperatures, Rain & Snow





The numbers here describe what the December weather in Anchorage, Alaska was like for every year since 2010. A series of tables gives December data by year for temperature, precipitation and snowfall.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many hot or cold days occurred each December. Then there's information on how much rain and snow actually landed this month during recent years, as well as how often Anchorage had wet or snowy weather.

The climate data come from weather measurements made at the Ted Stevens International Airport near downtown Anchorage.
