Umbrellas up: Longest heat wave of 2026 moves into Las Vegas

The big summer heat has arrived in Las Vegas. But it won’t be breaking any records.

Today’s forecast high is 104 degrees; it’ll be 107 every day through the weekend, the National Weather Service said. No heat records are expected to be broken. The last time Las Vegas saw a long stretch of 100-plus days was last August.

Harry Reid International Airport hit 106 on Wednesday, said Jenn Soulat of the NWS, making it the hottest day of the year. The record was 109, set in 2022. The average high for mid-June is 98, which was the temperature recorded at Reid on Tuesday.

Last week, Las Vegas reached 105 degrees for two consecutive days before dropping back into the 90s.

Interestingly, Arizona may see some monsoonal moisture this weekend, which could indirectly impact Southern Nevada, Soulat said. Tropical Depression Cristina is expected to strike Central America today, causing some of its remnants to spill into Arizona.

There are “slight (15-20%) chances for showers & storms” across the Arizona lower deserts Friday and Saturday, the NWS Phoenix office said in a post on X.

Soulat said it’s too early to tell if and when how the remnants could affect parts of Southern Nevada, including extensive cloud cover.

Monsoon season officially begins June 15 for the Southwest. In Southern Nevada, the season doesn’t get ramped up until July 1.
