Trader consensus on Polymarket tilts toward a high of 62-63°F for San Francisco on May 2, driven by the latest National Weather Service forecasts and model ensembles indicating persistent marine layer stratus over the Bay Area, limiting daytime heating despite weak high pressure aloft. Westerly winds of 5-10 mph are expected to advect cool, moist Pacific air, capping temperatures below climatological May averages of 65-67°F at official stations like KSFO airport. Close probabilities for 60-61°F reflect uncertainty in fog burn-off timing—earlier clearing could boost peaks toward 64°F via enhanced boundary-layer mixing, while prolonged cloud cover favors cooler outcomes. Watch NWS updates Friday for refined guidance from GFS and ECMWF runs.
