Hot and dry air mass sweeping across Los Angeles and nearby valleys
A dramatic spike in temperatures is hitting Southern California, pushing the region from a gloomy May gray into a potentially record-breaking heat wave. Beginning Friday, May 9, areas across Los Angeles County, particularly the San Fernando Valley and San Gabriel Valley, are forecast to sizzle under triple-digit temperatures.
According to meteorologist Rose Schoenfeld with the National Weather Service in Oxnard, this warm spell marks a sudden and extreme temperature jump, with values ranging 10 to 20 degrees Fahrenheit above seasonal averages.
Temperature outlook for key regions
On Friday, expect coastal areas like Santa Monica, Torrance, and LAX to climb into the mid-70s (about 24°C), while valley zones will push into the 90s°F (mid-30s°C). By Saturday, May 10, the heat will intensify further:
- Woodland Hills: 99°F (37°C)
- Burbank: 96°F (35.5°C)
- Anaheim: 94°F (34.5°C)
- Irvine: 87°F (30.5°C)
- Riverside & San Bernardino: 98°F (36.5°C)
Even along the coastline, traditionally tempered by the Pacific, the sun will dominate, with locals likely feeling the heat much more sharply than usual.
Forecasters urge caution as heat peaks
Although a formal heat advisory has not yet been issued, meteorologists are urging the public to remain cautious, especially during afternoon peak hours, when exposure to direct sun could increase the risk of heat-related stress. Residents are advised to keep hydrated and reduce outdoor exertion, especially in inland and valley areas where the heat will be most intense.
Cooler air returns by Mother’s Day
Just as fast as it arrived, the heat wave will retreat. On Sunday, May 11, Mother’s Day, temperatures will begin a gradual descent, and by Monday, May 12, a cool-down will sweep the region with highs falling back into the low to mid-70s°F (22–24°C). In fact, according to Schoenfeld, some locations may drop to below seasonal norms by up to 6°F (3°C) at the start of next week.
