Well, Tucson, we did it. A final, rainy push at the end of monsoon season knocked 2025 off the list as being one of the driest on record — but not by much.
A mere .03 inches kept this year’s monsoon from ranking as the 10th driest season, beaten narrowly by 1918’s 2.79 inches of total rainfall.
It was, however, a slow and dusty start.
Totals reported by the National Weather Service taken at the airport, where official weather records are kept, show that although a very small amount of rain was reported having fallen June 1, not another drop was recorded the rest of the month.
Luck would soon change. The month that followed was the season’s wettest.
July rains dropped hard on Tucson, making up 1.88 inches of the entire season’s 2.82 inch total, the weather service says.

There were 12 measurable rain events during July. But one storm that toggled July 15 and 16 dropped 1.35 inches of the month’s total rainfall. It marked the wettest 24-hour period of the 2025 season.
August rainfall (of which there were four measurable days) totaled .11 inches of precipitation. And September crept in with 10 days of rain totaling .83 inches, sufficient to knock 2025 off the driest season record list. The wettest day of the month was logged on Sept. 18, when .5 inches was recorded, the weather service says.
And while Tucson was just barely bumped off driest list by 2004’s 2.42 inches — ranking at 12th — there are other record-holding years that have kept their titles for decades, and even a century.

The top five driest seasons are as follows: 1924, 1.59 inches; 2020, 1.62 inches; 1973, 2.33 inches; 1989, 2.40 inches; and 2024 with 2.42 inches.
The rainfall totals pale in comparison to Tucson’s wettest monsoon months, which date back to 1921.
August rainfall (of which there were four measurable days) totaled .11 inches of precipitation. And September crept in with 10 days of rain totaling .83 inches, the weather service said.
The top five wettest seasons are as follows: 1964, 13.84 inches; 1955, 13.08 inches; 2021, 12.79 inches; 1921, 11.04 inches; and 1983 with 10.50 inches.
Now that the rain seems to have moved on — clearing the sky and welcoming back the Tucson sun — temperatures are expected to hover between the mid-high 90s (about five degrees above normal) and cool back down to normal temperatures as the weekend approaches.
Nighttime temps will fall to the mid-high 60s.
The thought of falling temperatures should be come as a delight, considering the summer of 2025 has been the fourth hottest summer on record, according to the weather service.
A mere .03 inches kept this year’s monsoon from ranking as Tucson’s tenth driest season, beat narrowly by 1918’s 2.79 inches of total rainfall.
This will lead us into an expected warmer and drier-than-normal winter for this year.
The weather service said that after a dry, summer monsoon season, the prospect of a dry winter under La Niña conditions is expected to continue — or worsen — drought conditions in the region.
There’s an increased chance for below-normal precipitation in the Southwest, including Tucson, the Climate Prediction Center’s outlook shows.
Consistent with the warmer temperature trend, Tucson is likely to experience fewer nights with freezing temperatures compared to the historical average.
This means fewer days protecting plants from frost and scraping icy windshields.
