San Francisco to Experience Warm Temperatures, Potentially Reaching 80s
US · Published May 19, 2026
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.

Why It's Important?

The warm and dry conditions could lead to discomfort for those sensitive to heat, particularly in inland areas where temperatures may approach 90°F (32°C). The low humidity levels could also increase the risk of dehydration and fire hazards, especially in areas away from the immediate coast. Residents in the South Bay and Santa Clara Valley should prepare for dry air and elevated temperatures.
