Number of Sunny Days
In the table below, the average number of Sunny Days for a city in Idaho 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.
Total Days With Sun is a sum of the Sunny plus Partly Sunny days. The rest of the days are mainly overcast, with at least 80% cloud cover. All the numbers are annual averages, made from years of weather watching.
| City | Sunny | Partly Sunny | Total Days With Sun |
|---|---|---|---|
| Boise | 5 | 6 | 11 |
| Lewiston | 3 | 5 | 8 |
| Pocatello | 4 | 6 | 10 |
Amount of Sun
Here's another way to look at how much sunshine a city 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.
| City | % Sun |
|---|---|
| Boise | 50 |
| Pocatello | 53 |
