Latest National Weather Service forecasts from the San Francisco Bay Area office project a high temperature of around 58-60°F on April 12, aligning with trader consensus favoring 58-59°F at 40% implied probability, due to persistent marine layer stratus clouds and moderate onshore winds suppressing daytime heating. Cool Pacific sea surface temperatures near 55°F combined with an upper-level trough pattern maintain cloudy conditions and low-level moisture, limiting solar insolation and capping peaks below climatological April norms of 62°F. Ensemble model runs from GFS and ECMWF show tight agreement on mild highs with 30-70% precipitation chances from scattered showers, though rapid burn-off could push toward 60-61°F; final observations from official stations like KSFO will resolve the market amid typical coastal forecast uncertainty.
