LAS VEGAS (KTNV) — The Las Vegas Valley got a reprieve from triple-digit temperatures on Tuesday after what proved to be the hottest July on record.

With an average temperature of 97.3 degrees, July 2023 was the hottest July recorded in Las Vegas, according to the National Weather Service.

The previous record was an average of 96.2 degrees in July of 2010.

Not only was July the hottest month on record in Las Vegas, it was the hottest month ever recorded in human history.

Temperatures in Las Vegas reached at least 110 degrees on 17 separate days in July, tying another previous record set in July of 1942.

Yet another record was tied during the 10-day stretch when temperatures measured at Harry Reid International Airport reached at least 110 degrees, from July 14 to July 23.

The last time Las Vegas recorded 10 straight days of temperatures at 110 degrees or above was June 17-June 26 in 1961.
