More record-breaking heat today in Las Vegas? Probably

There’s no relief from the heat coming today. Or tomorrow.

Tuesday’s forecast high is 95 degrees in Las Vegas, which would break the record of 89 set in 1940. It would be the seventh consecutive day of record-breaking heat in the valley.

Don’t expect the temperature to waver much during the next few days. Daytime highs are forecast to be in the mid-to-upper 90s, the National Weather Service said, peaking Wednesday with a high of 97. The average high for the valley in late March is in the low 70s.

Starting Thursday, the valley should experience a slight cooling trend, with highs in the low 90s, the NWS said. However, more records are expected to be broken. 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.

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.
