The average rainfall in Arizona is 7.11 inches per year. Of course there is less in the desert areas than in the fertile areas. The above rainfall is distributed over 113,909 square miles contained in Arizona.

The least rainfall is in June of each year, with only an average of 0.4 in, with the most being in July and August with about 2.8 in. These two figures are for Flagstaff.
