Las Vegas says goodbye to extreme heat as monsoon storms loom
The extreme heat is ending, but the monsoon storms are returning to the Las Vegas Valley.
The valley was under an extreme heat warning, which ended Saturday night. It began Wednesday.
The valley didn’t see any showers Saturday, but rain chances will continue to increase during the next few days, said Brian Planz of the National Weather Service. A wave of monsoon moisture from Arizona is expected to combine with “moisture coming from Baja” in Mexico, he said.
The valley hasn’t seen any significant rain since mid-July. The last time Harry Reid International Airport saw measurable rain was July 3, when it recorded .02 inches.
For 2025, the airport has seen 2.05 inches. The average is 2.27. A normal rainfall year in Las Vegas is 4.18 inches. The average August rainfall at Reid is 0.34 inches.
