National Weather Service forecasts for San Francisco International Airport (KSFO) project a high temperature near 66-69°F today under sunny skies and light west-southwest winds, driving trader consensus to 100% on 66°F or higher. This positioning reflects short-range model agreement from HRRR and GFS ensembles, showing a warming trend with morning lows around 51-52°F and ample daytime heating after typical marine layer burn-off. Current observations confirm clear conditions developing, aligning with May climatological normals where average highs hover near 66°F. Realistic challenges include persistent coastal stratus delaying clearing or unexpected gusty onshore flow enhancing evaporation cooling, though NWS guidance indicates low likelihood; intraday METAR updates and the evening climate summary will confirm the outcome.
