San Francisco to Experience Warm Temperatures, Potentially Reaching 80s
San Francisco and surrounding areas are set to experience warm and dry conditions on Tuesday, with inland regions like the North Bay and East Bay valleys expected to see highs in the upper 80s to low 90s. Cities such as Concord, Livermore, and parts of Napa County will be among the warmest. The South Bay, including San Jose and Silicon Valley, will likely reach the mid- to upper 80s. Around the bay, temperatures will depend on the timing of marine air. If the sea breeze arrives earlier, areas like San Francisco, Oakland, and Berkeley may stay in the 70s, but a later arrival could push temperatures into the low to mid-80s. Relative humidity will drop into the 20-30% range, making the air feel dry. Overnight lows are expected to be in the low to mid-50s.
