Unseasonable heat wave arrives in Los Angeles County
A sudden surge of heat is about to blanket Southern California, pushing temperatures into the triple digits this weekend and potentially shattering early May records. After a string of gray skies and drizzly mornings, Los Angeles County is bracing for a dramatic warm-up that will begin Friday, according to the National Weather Service.
Meteorologist Rose Schoenfeld, based in Oxnard, reported that valley temperatures will soar into the 90s°F (32–37°C) by Friday and could climb as high as 100°F (38°C) in the San Fernando Valley and San Gabriel Valley by Saturday. This marks a 15- to 20-degree swing above seasonal norms.
Forecast by region: Where the heat will hit hardest
In the San Fernando Valley, Woodland Hills could peak at a scorching 99°F (37°C), while Burbank is expected to hit 96°F (36°C). Along the Los Angeles coast, including Santa Monica, Torrance, and areas near LAX, residents will still feel a warm-up with highs in the mid-70s°F (24°C)—a notable contrast to recent chilly mornings.
In Orange County, Anaheim is forecasted to reach 94°F (34°C), while Irvine will hover around 87°F (31°C). The Inland Empire, consistently the hottest during warm spells, will live up to its reputation with Riverside and San Bernardino expected to hit 98°F (37°C).
“It’s going to feel unusually hot, even in coastal areas,” said Schoenfeld. The temperature spike is expected to push some areas well above long-term averages for early May.
Safety concerns and Sunday relief
Although a formal heat advisory may not be issued, forecasters warn against prolonged outdoor activity during peak afternoon hours, and they urge people to stay hydrated. These conditions can affect vulnerable populations, especially those without access to air conditioning or shaded areas.
The heat won’t last long. By Sunday—Mother’s Day—temperatures will ease slightly, and by Monday, the region will cool dramatically, with highs falling back into the low to mid-70s°F (21–24°C). In fact, temperatures could dip below seasonal norms by 2 to 6 degrees, marking a sharp end to the brief heatwave.
