Forecast Heat Risk for California

UPDATED Monday, August 3rd, 2026: The Heat Advisory is now in effect until 8 PM PDT Wednesday. Dangerous Heat will continue in the San Joaquin Valley, west side hills, lower Sierra Nevada foothills, Lake Isabella, and the Kern River Valley until at least Wednesday. Widespread triple digit heat will persist in these areas with overnight lows in the 70s at the hottest locations.

Monday, August 3, 2026 - The Extreme Heat Warning is now in effect for the Indian Wells Valley, the Mojave Desert and Mojave Desert Slopes in eastern Kern County through 8 PM Wednesday. Afternoon highs up to 112 degrees are expected, and morning lows in the mid 70s to lower 80s will provide little relief. Stay hydrated, use air conditioning and remain in cool places during the day, and avoid outdoor activities during the warmest parts of the day.

A Moderate Risk for Elevated Fire Danger will persist across much of Central California through at least midweek with the combination of seasonably dry vegetation and very low humidity. Most areas will see winds less than 15 mph, but a few locations will see gusts from 15-25 mph.

Hot weather will continue for the remainder of the work week. A Extreme Heat Warning is in effect through 8 PM Wednesday for the Desert region of eastern Kern county. The remainder of interior central California has a Heat Advisory in effect through 8 PM Wednesday. Hot temperatures from the low 100s to the 110s will continue for the remainder of the week with a slight cooldown possible Thursday and Friday.

The Heat Risk will remain in the Moderate to Major category over much of California and the Western United States the next few days. Make sure to follow precautions to beat the heat including taking frequent breaks and staying hydrated.
