September brings scorching heat over Southern California and forecasters are predicting record-breaking temperatures.
From Wednesday through Labor Day weekend, the National Weather Service predicts temperatures could reach 115 degrees in some parts of Southern California. It will be the region’s longest and warmest heatwave of the year, said David Sweet, a weather forecaster with the National Weather Service in Oxnard. The conditions are expected to continue through Monday, although “we don’t see an end at this time,” Sweet said.
Here’s what you need to know.
Much of Southern California, including Los Angeles County, Ventura County and the southern coast of Santa Barbara County, is under excessive heat surveillance from 11 a.m. Wednesday to 8 p.m. Monday.
For Riverside, Orange and San Bernardino counties, the warning goes into effect at 10 a.m. Tuesday and lasts until 8 p.m. Monday.
“In general, Wednesday through Monday on each of these days, we can see an elevation of 112 in the valleys, mountains, foothills, and deserts, especially in the valleys and deserts,” Sweet said.
The hottest conditions are expected on Thursday before cooling slightly over the weekend, although conditions are still warm and will rise again on Sunday.
In LA County, temperatures could reach 105 in Woodland Hills on Thursday and rise to 110 on Sunday. Lancaster in Antelope Valley could reach as high as 108 on Thursday and Sunday. In Santa Clarita, Newhall could hit 106 on Thursday and 108 on Sunday.
Downtown Los Angeles could hit a high of 93 on Thursday, 94 on Saturday and as high as 100 on Sunday.
In Ventura County, Ojai is expected to hit 105 on Thursday and 107 on Sunday, while Fillmore is expected to hit 102 on Thursday and 106 on Sunday.
High temperatures on Los Angeles County beaches are expected to hover in the mid-80s to mid-90s over the next few days.
Temperatures in San Bernardino, Orange and Riverside counties will rise through Friday and rise again Sunday and Monday, said Casey Oswant, a weather forecaster with the National Weather Service in San Diego.
Temperatures of between 100 and 106 degrees are expected in Riverside by Friday. It could reach as high as 108 by the weekend.
In the Coachella Valley, highs remain between 110 and 115 degrees. In the high deserts, in areas like Apple Valley and Lucerne Valley near Victorville, temperatures are likely to range between 105 and 110 degrees.
Coastal conditions are at their toughest on Sunday and Monday with highs between 85 and 90 degrees.
People won’t get much relief overnight either, as temperatures are expected to cool only slightly, Oswant said.
