Number of Sunny Days

In the table below, the average number of Sunny Days for a place in Alaska is the total days in a year when the sky is mostly clear. This includes the days when cloud covers up to 30% of the sky during daylight hours.

Partly Sunny Days have cloud covering from 40% to 70% of the sky during the daytime. The rest of the days are mainly overcast, with at least 80% cloud cover. Total Days With Sun is a sum of the Sunny plus Partly Sunny days. All the numbers are annual averages, made from years of weather watching.

You can jump to a separate table for each region of the state: Southeast, South - Central, Southwest and Far North Alaska.

Amount of Sun

Here's another way to look at how much sunshine a place gets. The % Sun number measures the percentage of time between sunrise and sunset that sunshine reaches the ground. Again, these amounts are yearly averages based on many years of weather observations.
