Number of Sunny Days

In these tables, the average numbers of Sunny Days for places in Utah are the total days each month or 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.

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 averages, made from years of weather watching

Amount of Sun

Here's another way to look at how much sunshine Utah normally gets. The % Sun numbers measure the percentage of time between sunrise and sunset that sunshine reaches the ground. Again, these amounts are averages based on decades of weather observations.

The Total Hours figures are the average number of sunny hours that Salt Lake City has each month or in a year, taken from data collected for 1961 to 1990.
