Average Sunshine in Montana for July
Number of Sunny Days
In the table below, the average number of Sunny Days for a city in Montana 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 July 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.
