Trader consensus clusters around 74-77°F peaks for San Francisco's March 27 high, driven by ensemble forecasts from NOAA's GFS and ECMWF models projecting mid-70s amid a potent upper-level ridge amplifying downslope warming from the east. This setup overrides the city's typical marine layer fog, which historically caps late-March highs near 63°F, but recent runs show variable stratus burn-off: quicker dissipation favors 76-77°F via enhanced solar insolation, while persistent coastal clouds differentiate toward 72-75°F by limiting diurnal heating. NWS guidance leans 74°F, with offshore high pressure strengthening per latest 12z updates, though afternoon sea breeze onset adds uncertainty to the tight race.
