Average Sunshine in Alaska for May
Number of Sunny Days
In the tables below, the average number of Sunny Days for a place in Alaska is the total days this month 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 during May 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 averages, made from years of weather watching, for total days in the month.

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 monthly averages based on many years of weather observations.
| Place | % Sun |
|---|---|
| Anchorage | 50 |
| Juneau | 39 |
| Nome | 50 |
