Las Vegas to finish March with more record-breaking heat

Las Vegas struggled with record heat on the first weekend of March. It’s going to end the month the same way: hot, record-breaking temperatures.

Expect daytime highs to be in the low 90s this weekend, with a forecast high of 92 degrees today, the National Weather Service said. The record for Friday is 88, set in 2022.

Thursday’s high was five degrees cooler than Wednesday’s record-breaking 98, the hottest day of the year. Morgan Stessman of the NWS said the heat dome over the Southwest is starting to weaken and temperatures are trending downward. The average high for the valley in late March is in the low-to-mid 70s.

Through Wednesday, the valley had witnessed eight consecutive days of record-breaking heat, a streak the valley has never seen, the NWS said.

Las Vegas probably won’t see temperatures in the upper 80s until 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.
