A shallow marine layer of roughly 1,000 feet, combined with persistent onshore northwest flow and patchy coastal stratus, is the dominant driver keeping overnight minimums near or slightly below the 58°F August climatological average for San Francisco. NWS guidance and recent model runs point to lows in the mid- to upper-50s under mostly cloudy to hazy conditions, with limited radiative cooling due to the inversion and marine influence. This setup supports the market’s emphasis on the 58-59°F and 54-55°F bins while the elevated probability on 49°F or below reflects trader awareness of forecast uncertainty, potential marine-layer deepening, and historical variability in coastal minimums when stratus lingers. Updated NWS briefings and morning observations will refine these ranges ahead of the daily low’s official recording.
