National Weather Service forecasts and ensemble model guidance from GFS and ECMWF project San Francisco's highest temperature at KSFO on April 1 around 64-67°F under weak high pressure and moderate onshore flow, yet trader consensus favors the cooler 60-61°F outcome at 37.5% implied probability, reflecting persistent marine stratus typical for early April that often delays afternoon burn-off and caps peaks despite inland warming. Recent March 29 Area Forecast Discussion highlights strengthening northwest winds and potential light coastal drizzle, tempering model warmth amid climatological averages of 63°F for April 1 highs. With genuine uncertainty in stratus extent, watch daily NWS updates and new model runs through March 31 for shifts in these closely contested mid-60s probabilities.
