Trader consensus on Polymarket reflects tight uncertainty around a mid-60s high temperature at San Francisco International Airport (KSFO) on April 6, with 64-65°F and 66-67°F each at 26.5% implied probability, driven by National Weather Service forecasts projecting highs near 65°F under a developing high pressure ridge following mid-week rain. Persistent marine layer stratus and moderate onshore winds temper warming potential, limiting burn-off and keeping coastal sites like KSFO cooler than inland areas, per recent Area Forecast Discussions from the San Francisco Bay Area office (KMTR). Ensemble guidance from GFS and ECMWF models shows minor spread in afternoon mixing depths, explaining the near-even split between these bins amid climatological April norms of 63-66°F. New model runs and morning soundings by Sunday could refine odds further.
