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 19 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 tilts toward mid-60s°F highs for San Francisco on April 19, with 66-67°F leading at 26.5%, reflecting latest National Weather Service guidance and model consensus from GFS and ECMWF projecting peaks near 65-67°F under a seasonably warm pattern. A weak upper-level ridge promotes sunny afternoons after morning marine stratus, but persistent onshore flow and coastal boundary layer depth introduce uncertainty—thicker fog favors 64-65°F, while gusty offshore winds could enhance mixing for 68-69°F. April climatological normals (64-66°F highs) reinforce this tight clustering, with historical analogs showing 2-3°F swings from stratus burn-off timing. Monitor NWS updates and 12z model runs on April 18 for refinements ahead of resolution.
