Stuck in the 90s: Las Vegas to endure more record-breaking heat

Breaking heat records has turned into a broken record in Las Vegas. Cue the music: the valley should see another day of historic March heat today.

The forecast high for Wednesday is 96 degrees, which would break the daily daytime high record of 90, set in 2022. It would be the eighth consecutive day of record-breaking heat in the valley.

Fortunately, a little bit of relief is on the way. Daytime highs are forecast to be in the low 90s for Thursday and Friday, the National Weather Service said.

However, more records are expected to be broken. The average high for the valley in late March is in the low-to-mid 70s.

Las Vegas may not see temperatures in the upper 80s until Sunday or Monday. By the end of this month, the valley likely will have recorded at least 10 90-degree days, an all-time record.

Blistering temperatures associated with a heat dome, a rare event in March, continue to break records across the Southwest.

Tracking the hot streak

Tuesday: 96 (old record: 89 in 1940)

Monday: 96 (89 in 1940)

Sunday: 93 (91 in 2004)

Saturday: 96 (92 in 2004)

Friday: 97 (90 in 2004)

Thursday: 95 (90 in 2017)

Wednesday: 94 (90 in 2017). Note: The high surpassed the previous all-time March high of 93 that had been set March 26, 2022.

The intense March heat in Las Vegas is a continuation of a theme, as the month started out with record-breaking heat. And last month was the second-warmest February in the valley since record-keeping began in 1937. January 2026 was the fifth-warmest January on record.
