This market will resolve to the temperature range that contains the highest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 17 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the San Francisco International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ca/san-francisco/KSFO. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket prices a 41% implied probability for San Francisco's highest temperature at San Francisco International Airport (KSFO) reaching 68-69°F on April 17, driven by the latest National Weather Service (NWS) and NOAA forecast models projecting a peak near 68°F under building upper-level high pressure. This setup reduces persistent marine stratus cloud cover—typical of San Francisco's cool coastal microclimate influenced by Pacific upwelling—allowing earlier fog burn-off and greater solar heating inland before afternoon sea breezes strengthen. Recent model runs from GFS and ECMWF show consensus for seasonably warm conditions above the April normal of 66°F, following similar highs around 69°F observed April 16. Uncertainties remain in exact burn-off timing and wind shear, with NWS updates expected hourly; resolution hinges on official KSFO observations.
