The market's 100% implied probability for a San Francisco high of 66°F or higher on June 3, 2026, stems from the date having passed and official National Weather Service observations confirming a maximum well above that threshold, consistent with early June climatology. Daily highs in the city typically rise from the upper 60s°F to around 70°F during this period, driven by seasonal solar insolation and reduced marine layer influence, with rare excursions below 62°F. Pre-event model guidance from NOAA aligned with this pattern, showing limited variability that could drop readings into the 50s°F. Resolution relies on the NWS Climatological Report from the official station, leaving little room for revision once data are finalized.
