Trader consensus on Polymarket assigns a 63% implied probability to a high of 76°F or higher in San Francisco on March 29, reflecting National Weather Service guidance near 71°F but buoyed by model runs from GFS and others projecting mid-to-upper 70s amid a persistent upper-level ridge over California. This pattern promotes subsidence warming, clear skies, and limited marine layer influence at KSFO (San Francisco International Airport, the resolution source via Weather Underground), allowing greater solar insolation far above the March climatological normal of 62°F. Recent record-shattering March heat— including 86°F at SFO earlier this month—has conditioned traders to this dynamic, though uncertainty lingers from potential stratus persistence capping peaks at 74-75°F (20.5%). Watch for afternoon NWS updates on March 28.
