The official stats confirm the way it feels: Tucson’s monsoon rainfall is slightly below average so far this summer.
As of Monday afternoon, the city had 1.88 inches since the monsoon season officially began on June 15, all of it in July, the National Weather Service says.
That’s .17 inch below normal for the season so far, as the monsoon approaches its Aug. 7 halfway point.
Last July, the weather service recorded 3.41 inches, nearly 2 inches of which came from a single storm system that knocked out trees and caused damage across central and northwest Tucson.
This month, after a week of dryness that put us behind, chances of rain return this week, with a 20% chance Tuesday, a 30% chance Wednesday and a 40% chance on Thursday, according to the weather service.
Temperatures are expected to remain in the low hundreds this week, with a high of 104 degrees Tuesday, 103 Wednesday and 100 Thursday before rising to 102 Friday.
“We’re seeing a typical pattern for monsoon throughout the rest of August,” weather service forecaster Kevin Strongman said Monday. “It’s looking like equal chances, so it could be wetter, could be drier, but it’s looking like a typical August pattern.”
In 2024, the city experienced a split monsoon season — half wet and half dry.
Tucson recorded 5.39 inches of rain in the first half of last year’s monsoon (June 15 to Aug. 8), and just 0.41 inch in the second half (Aug. 9 to Sept. 30), the weather service reported.
