Trader consensus on Polymarket prices 68-69°F highest temperature in San Francisco on April 17 at 45.5% implied probability, closely tracking the latest National Weather Service guidance for a high near 68°F at San Francisco International Airport under partly sunny skies with light north winds. This positioning reflects the NWS Area Forecast Discussion updated April 15, which anticipates seasonably warm conditions Friday into the weekend, extending the Bay Area's record hottest March amid a stable upper-level ridge suppressing deeper marine layer intrusion. Typical spring coastal fog and onshore flow cap extremes, with historical April highs averaging 64°F; however, model consensus shows low uncertainty barring sudden wind shifts or cloud persistence. Watch afternoon forecast refinements and initial observations for potential adjustments.
