It wasn’t a record but Tuesday was the hottest day of 2025 in Las Vegas. Well, it tied for the hottest day of the year.

The temperature reached 112 degrees at 4:32 p.m. at Harry Reid International Airport, the National Weather Service said. The record is 115, set in 1937.

The airport hit 112 on July 14.

The NWS said the temperature will be slightly cooler Wednesday, with a forecast high of 110. The valley is under an extreme heat warning until 8 p.m. Wednesday.

The weather service is predicting “dangerously hot conditions,” with high temperatures from 108 to 114 degrees, for Las Vegas and nearby areas, including Pahrump, Mesquite and Lake Mead National Recreation Area.

Residents are advised to drink plenty of fluids, wear lightweight clothing, stay out of the sun and make sure children and pets are not left in unattended vehicles.

In response to the extreme heat warning, Clark County has activated cooling stations, which are open now through Thursday. A list of stations is available at helphopehome.org.

Last week, the Clark County coroner’s office reported at least 87 heat-related deaths so far this year. Oddly, last month was the coolest July that Las Vegas has seen since 2015.

Where’s the monsoon?

The NWS, in a post on X, said this summer’s weather pattern “has favored dry conditions thanks to an active jet stream” across the Pacific Northwest. The monsoon moisture has stayed “well to our east, but has also kept the summer cooler than recent years.”

Wetter conditions have “largely favored” New Mexico and the Southern Plains states.

The agency said Harry Reid airport has recorded only 0.02 inches of rain since June 15, the beginning of monsoon season. The normal, to date, is 0.50.

In comparison, Kingman, Ariz., has seen 0.45 inches (normal: 1.35) and Barstow, Calif., has seen nothing (normal: 0.34).
