San Francisco Oakland San Jose, CA, July 30, 2026 —

California is anticipating a significant heat wave this weekend, with temperatures expected to climb across the state. However, the Bay Area is forecast to experience a notable temperature gradient between its coastal and inland regions.

Coastal cities, including San Francisco and Oakland, are projected to have high temperatures in the high 70s and 80s. These milder conditions near the coast are attributed to the influence of marine layers, which are expected to keep temperatures closer to 60 degrees in some areas.

In contrast, inland communities are bracing for much hotter weather. Areas like Santa Rosa and Livermore could see temperatures reaching the upper 90s, with some forecasts predicting potential triple-digit readings.

In addition to the heat, the National Weather Service has issued advisories for coastal areas, warning of an increased risk of sneaker waves and dangerous rip currents throughout the weekend. Visitors and residents are urged to exercise caution near the ocean.

Looking ahead, weather models indicate the possibility of another, potentially more intense, heat wave developing around August 5-8. This subsequent heat event could affect Northern California more severely, though specific impacts are still subject to evolving forecasts.
