112, again: Las Vegas endures hottest day of 2025

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 for Aug. 12 is 115, set in 1937.

The airport also hit 112 on July 14. The valley was under an extreme heat warning Tuesday and Wednesday.

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 weather service, 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 last time Harry Reid airport saw measurable rain was July 3, when it recorded .02 inches.

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