The inland Bay Area heat advisory now runs until 10 p.m. on Wednesday, October 7, in Pacific Daylight Time—two days beyond the endpoint in our October 3 edition.
San Jose, the East Bay’s interior valleys and much of the North Bay remain affected. [1]
San Francisco’s advisory still ends on Sunday, October 4, at 10 p.m. PDT. Sunday’s coverage now also includes the Peninsula Coast, coastal North Bay including Point Reyes, and the Big Sur coast. A trip towards the ocean therefore does not automatically avoid the advisory. [1]
For the return to work, plan cooling, hydration and outdoor exertion around the longer inland spell. NWS forecasts inland highs from the mid-90s to low-100s Fahrenheit, with limited overnight relief; that is not San Francisco’s temperature forecast. Check the current warning and destination forecast before leaving. [1][2]
