Summer 2025 was hot in Las Vegas. But just how hot was it?
Las Vegas had above-normal temperatures and below-normal precipitation this summer, according to a National Weather Service report released this week.
But at least it wasn’t the summer of 2024, the hottest in Las Vegas history.
“This was the 10th-warmest summer on record,” meteorologist Matt Woods said.
The average temperature was 92 degrees. The normal average is 90.5 degrees.
To valley residents, this summer felt considerably cooler than recent summers. Las Vegas had its coolest July in 10 years, and fewer heat records were broken. June and August were above normal but not extremely hot.
Woods explained that this past summer season, from June through August, saw little rain, with only 0.02 inches falling at Harry Reid International Airport on July 3. The summer average is 0.74 inches.
And so far, this is the fourth-driest monsoon season on record. The Las Vegas monsoon season runs from July 1 to Sept. 30.
“We didn’t have a favorable monsoon pattern until late August,” Woods said, which was one reason the summer was warmer than normal.
And the “warm and dry” trend is likely to continue through fall and the rest of this year, Woods said.
There’s a 50 percent chance of above-normal temperatures in the September-November period, he said, referring to Climate Prediction Center forecasts. And there’s a 40 percent chance of below-normal precipitation.
