Despite the clouds, rain and thunder hovering over Tucson the past few days, this year’s monsoon season will likely go down as one of the Top 10 driest, the weather service says.

As of Sept. 26, monsoon rain totals have been a dismal 2.76 inches.

The season ends on Sept. 30, making it almost impossible to hit the normal precipitation total: 5.56 inches.

Last year, the 2024 season dropped 5.80 inches of rain here during the official monsoon period, which begins June 15, the National Weather Service in Tucson says.

A typical rainy summer season here can vary widely, 2025 has shown.

The year’s wettest month was July, with a total of 1.88 inches recorded at the airport, where official weather records are kept.

This might not sound like much, but in 1924, the most anticlimactic (and driest) monsoon β€œdumped” a total of 1.59 inches over Tucson β€” period. The entire season.

This year’s low precipitation totals have put 2025 at 10th on the monsoon ranking, but it’s not to say recent rainfall hasn’t helped.

Rain catches showed that some areas across the Tucson area received between .04 and .16 inches late last week. Adding that to current rainfall totals barely tipped the scale when it came to reaching normal monsoon levels.

Reaching too high over the average, however, can cause flash floods, swift-flowing washes, and other disasters. Take 2021, for instance, when 12.79 inches of rain fell over the Tucson area in a matter of months.

While the rain may be subsiding, higher temperatures are not.

Sunday will bring a limited chance of showers and a below-average temperature, the weather service says, but Tucson will warm up next week when monsoon season comes to an end.

As drier winds make it to Tucson, temperatures could hit as high as the mid-90s next week, the forecast shows.
