Trader consensus on Polymarket heavily favors highs of 60-65°F for San Francisco on April 1, with 62-63°F and 60-61°F nearly tied at around 29% implied probabilities each, driven by National Weather Service forecasts highlighting a persistent shallow marine layer—cool, moist Pacific air capped by a temperature inversion—that has redeveloped after mid-March's rare heat wave. This stratus deck typically suppresses coastal peaks to the low-to-mid 60s, aligning with historical April 1 averages near 63°F and recent model consensus from GFS and ECMWF runs showing limited inland heat advection. Differentiating factors include morning fog burn-off timing: early clearing could boost odds for 64-67°F via solar heating, while prolonged onshore flow favors cooler outcomes; new NWS updates and overnight model refreshes expected within 24 hours may sharpen this uncertainty under transitioning ENSO-neutral conditions.
