Here come the 110s: July heat wave moves into Las Vegas

Las Vegas has not seen 110-degree temperatures this year. That is about to change.

Starting today, the valley is expected to hit 110 or above for the next four days. Today’s forecast high is 110; Thursday is 111, Friday is 110 and Saturday is 111. Tuesday’s high at Harry Reid International Airport was 108.

The last time Las Vegas saw 110 degrees was Aug. 21, 2025, the latest date ever recorded for such a high temperature. Last month, the valley recorded 109 on June 16 and June 23. The average first 110-degree temperature is July 1.

Ashley Nickerson, a meteorologist at the National Weather Service office in Las Vegas, said an “area of high pressure is building over the Southwest,” causing temperatures to spike this week.

But it won’t be anything like the record-breaking heat wave in 2024. Las Vegas hit 120 degrees on July 7, 2024, the hottest day in its history. No records are expected to be broken this week. The average high for early July is 104.

Cooling stations activated

Clark County said it has activated cooling stations at community centers, libraries and other buildings across the valley.

The cooling stations’ hours will vary depending on the location, the county said. The stations will include several locations in Las Vegas, North Las Vegas, and Henderson.

The stations are open to anyone in need of respite from the heat, the county said. Additional information can be found at the Southern Nevada Homelessness Continuum of Care’s website at helphopehome.org/get-help/, the county said.

Monsoon storms on horizon?

Conditions will be a bit cooler by Sunday as “a hint at monsoon moisture” enters Southern Nevada, which will cause a drop in temperatures. The forecast high for Sunday is 108.

Nickerson said chances for monsoon storms will increase Monday and Tuesday, but it’s too early to tell how strong those chances will be.

The summer monsoon season in Southern Nevada runs from late June into September. Julie Phillipson, lead meteorologist at the NWS, said it is hard to say whether the region will see an increased number of thunderstorms this summer, but it is possible given the current setup in the atmosphere.

“There is a strengthening El Niño right now, so that could indicate a more active Eastern Pacific tropical storm season, which could give us more opportunities for significant monsoon events, but right now we have to wait and see,” Phillipson told the Review-Journal earlier this week.

The National Oceanic and Atmospheric Administration is forecasting a 40 percent to 50 percent chance of above-normal precipitation in Southern Nevada this month and a slightly lower chance for above-normal precipitation through September. Normal precipitation in Las Vegas averages 0.38 inch of rain in July, 0.32 inch in August and 0.32 inch in September, according to data from NOAA.
