Current National Weather Service guidance and ensemble models indicate a moderately mixed marine layer of roughly 1,000–1,800 feet over the Bay Area on July 24, with persistent onshore westerlies and cool Pacific waters suppressing maximum temperatures near the July climatological mean of 68°F. Trader consensus favoring the 68–69°F and 70–71°F brackets reflects tight model clustering around modest afternoon warming under high pressure, tempered by uncertainty in layer depth and wind strength overnight. A shallower inversion or reduced onshore flow could allow peaks in the low 70s, while renewed stratus or stronger sea breeze would anchor readings in the mid-to-upper 60s. Final resolution hinges on official observations at the San Francisco International Airport station.
