Trader consensus tilts slightly toward 66°F or higher at 47% implied probability over 64-65°F at 40%, driven by the latest National Weather Service point forecasts for San Francisco International Airport (KSFO) projecting highs near 65-68°F amid typical May marine layer conditions. Morning observations show temperatures starting around 52°F under partly cloudy stratus decks, with west winds of 10-15 mph fostering a low-level temperature inversion that caps warming, though partial afternoon clearing could push peaks into the upper 60s per some GFS ensemble members. ECMWF runs show minor divergence on burn-off timing, while historical May averages at KSFO hover near 66°F; monitor hourly METAR reports through sunset around 8:10 PM PDT for the official daily maximum.
