California heat forecast raises fire and health risks for July 4

A holiday weekend weather outlook for California shows near‑normal temperatures along the coast, while inland valleys and mountains are set to run warmer than usual. Coastal cities such as San Francisco and Los Angeles are expected to see highs in the 60‑70 °F range, whereas the Central Valley and desert regions, including the Coachella Valley, could reach the low 100 °F with mid‑week peaks of 110‑115 °F. The National Weather Service warns of moderate to major heat‑related illness risk for vulnerable populations and heightened fire danger due to dry vegetation, though no watches, warnings or advisories are currently in effect.

In the Coachella Valley, the forecast predicts steady warming after the holiday, with desert temperatures climbing into the 110‑115 °F range by mid‑week. The combination of extreme heat and dry conditions presents a notable risk for both public health and wildfire ignition across the region.
