Forecasters are predicting temperatures at or near triple digits through Labor Day and into next weekend across Riverside County.
On Sunday, temperatures reached a high of 109 in the Coachella Valley, 89 in the Riverside metropolitan area and 83 in the Temecula Valley.
The Coachella Valley was expected to reach up to 113 Sunday, with light winds of 10 mph. Similar triple-digit temperatures are expected there throughout the week.
A few degrees of cooling is expected in the deserts on Labor Day due to the possibility of an influx of monsoonal moisture, according to the National Weather Service. Downtown Riverside was expected to reach 101 and the Temecula Valley was expected to reach 97 on Labor Day.
By Wednesday, the entire county will reach triple-digit temperatures that will rise a few degrees by Thursday and Friday, according to the NWS.
“We’ve been hinting at some hot weather expected later this week. Our confidence is increasing in seeing highs near 10 to locally 15 degrees above average,” the NWS posted Sunday on X. “The time is now to prepare for the incoming hot weather!”
The hot, dry weather will also create elevated fire conditions across the mountains, valleys and deserts this week.
