Meteorologists are forecasting a 33–50% chance of above-normal monsoon rain across most of Arizona this summer, 12News reported Tuesday.
The monsoon season officially began June 15 and is expected to end in mid-September, according to O'Odham Action News, which also reported the outlook calls for above-normal precipitation statewide. The National Weather Service separately predicts Phoenix could see a stronger monsoon this season, though above-normal temperatures are also in the forecast.
For Scottsdale and Paradise Valley property owners, a heavier monsoon season carries practical implications: drainage infrastructure, landscaping, and flat-roof commercial properties face elevated risk during above-average rain years. Scottsdale's monsoon rainfall total in a recent prior season came in at 2.65 inches, slightly above its historical norm, per Phoenix New Times.
The onset of the 2026 monsoon is tracking near-normal, generally expected from the last week of June into the first week of July, according to Arizona Weatherman.
The National Weather Service's Flagstaff office maintains a dedicated monsoon information page with updated outlooks as the season progresses.
