Chilling out: Las Vegas sees coolest July in a decade

It’s possible that you recently noticed your car only took a few minutes to cool down, compared with the eons it took last July.

You would not be wrong in realizing that.

Last month was over 7.5 degrees cooler than July 2024 and in fact was the coolest July the city has seen since 2015, according to the National Weather Service.

A cooling in July

The weather service said the average temperature for July 2025 was 92.5 degrees at Harry Reid International Airport (where the weather service tracks temperatures,) just under the ‘normal’ of a couple ticks over 93 degrees.

This year, while the heat was still noticeable, it was a departure from last July. Over the same stretch in 2024, Las Vegas saw all-time records. With a blistering mean of 99.9 degrees — 6.5 degrees above average — and a record of 120 on July 7, 2024, last year was historic.

Though at least one record was left unbroken: the stretch of 66 consecutive days over 100 degrees set in 1944.

Last year was only 64 days straight, falling short of the record.

August outlook

While July provided a small reprieve from the typical, August — at least its first week — will mark a return to higher temperatures for Las Vegas, forecasters said.

The weather service said overnights will turn warmer — between the high-70s and mid-80s — while daytime temperatures will soar between the low 100s all the way to 110 on Aug. 7, which would be approaching the daily record of 111 set in 2009.

Typical summers in Las Vegas

When looking at the 1991-2020 climate normals for the Las Vegas Valley provided by the weather service, a normal July day sits around 105, with overnight lows in the mid-to-lower 80s.

The warmest day of the month, officials said, was on July 14 with 112 degrees. By contrast, the coolest temperature registered in the month was 75 degrees, which the weather service said occurred on July 26 and 27.

Officials noted that, while Harry Reid was mostly dry in July, some “heavy downpours” in the northwest valley did result in flooding on July 18.

On the first day of July, strong winds from a dust storm and thunderstorms left thousands of residents without power and created a mess around the Las Vegas Valley as monsoon season arrived.
