Number of Sunny Days
In the table below, the average number of Sunny Days for a city in Wisconsin 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 April 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.
| City | Sunny | Partly Sunny | Total Days With Sun |
|---|---|---|---|
| Green Bay | 6 | 8 | 14 |
| La Crosse | 7 | 7 | 14 |
| Madison | 6 | 8 | 14 |
| Milwaukee | 6 | 8 | 14 |

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 |
|---|---|
| Green Bay | 56 |
| Madison | 52 |
| Milwaukee | 53 |
