The extreme heat bearing down on Beverly Hills, Bel Air and Holmby Hills will not let up this week. The National Weather Service extended its Extreme Heat Warning through Saturday, Aug. 8, three days beyond the original Wednesday, Aug. 5 end date, according to the Los Angeles County Department of Public Health.
The updated advisory, issued Tuesday, Aug. 4, also includes the Santa Susana Mountains in the Heat Advisory for the first time, with coverage running since Monday, Aug. 3. That lower-tier alert now covers the East San Gabriel Mountains, Western San Gabriel Mountains/Highway 14 Corridor, Northwest LA County Mountains along the Interstate 5 Corridor and the Santa Susana range, all through Saturday.
For canyon residents in Bel Air and the hillside neighborhoods above Beverly Hills, the combination of sustained high daytime temperatures and unusually warm overnight lows compounds both health and wildfire risk. As we reported in our Eaton Fire investigation coverage Aug. 4, a Southern California Edison tower caused that blaze, underscoring how dry, hot conditions can turn infrastructure failures into fast-moving fires.
Who is at risk
Los Angeles County Health Officer Dr. Muntu Davis said in the Aug. 4 advisory that heat kills more people in the United States annually than floods, storms and lightning combined. Those at highest risk include older adults, young children, outdoor workers, athletes, individuals with chronic medical conditions, those who live alone, pets and anyone without air conditioning. Warm overnight temperatures are especially dangerous because they prevent the body from recovering after a hot day.
When to call 911
Residents should call 911 immediately if they or someone nearby shows any of these symptoms: body temperature of 103°F or higher, dizziness, nausea, passing out, headache, fast and strong pulse, confusion, or hot, red, dry or damp skin.
Staying safe through Saturday
LA County Public Health recommends:
- Drink water throughout the day, even when not thirsty.
- Avoid outdoor activity during peak heat hours.
- Wear lightweight, light-colored clothing with a hat and sunscreen rated SPF 15 or higher.
- Keep your home cool or go to an air-conditioned space.
- Never leave children or pets in a vehicle. As of Aug. 2, 17 children had died in hot cars nationwide in 2026.
- Check on neighbors who live alone or have chronic conditions.
For those without air conditioning, the county suggests cool showers, minimizing stove and oven use, and visiting a library, cooling center or shopping mall.
Cooling resources
Free cooling centers, splash pads and community pools are open across LA County. Residents can find the nearest location at ready.lacounty.gov/heat or by calling 211, which operates around the clock. The NWS HeatRisk map at wpc.ncep.noaa.gov/heatrisk lets residents check heat risk specific to their neighborhood, factoring in how unusual the temperatures are for this time of year and local vulnerability data.
The warning remains in effect through Saturday evening.
