Extreme Heat Warning Issued for Southern California: Record Temperatures Expected
US · Published Jul 30, 2026
Southern California is bracing for an extreme heat event starting Friday, July 31, and lasting through Sunday, August 2,
The National Weather Service has issued an extreme heat warning for much of the region, excluding coastal areas. High pressure over Arizona is expected to expand westward, driving temperatures approximately 10°F (5.5°C) above normal. Forecasts predict highs ranging from 95°F to 115°F (35°C to 46°C) in valleys and deserts, with some areas potentially nearing 120°F (49°C). Overnight temperatures will remain elevated, increasing the risk of heat stress. Additionally, humidity levels may rise later in the week, exacerbating discomfort. The heat wave is also expected to heighten wildfire risks, particularly in foothills and lower mountain areas.

Impact & Risks

The extreme heat poses significant health risks, including heat illness and stress, especially for vulnerable populations such as the elderly and those with pre-existing conditions. Elevated nighttime temperatures will limit recovery from daytime heat exposure. Wildfire risks are heightened due to critically dry vegetation, particularly in foothills and lower mountain regions. Coastal areas may experience hazardous surf conditions due to a south swell from Hurricane Genevieve, with lifeguards warning of strong rip currents and large waves. Power outages in Calabasas during the heat wave have sparked concerns among residents, further complicating safety measures.
