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 27 Mar '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 closely splits between 76-79°F highs for San Francisco on March 27, reflecting the tight spread in latest National Weather Service and ensemble forecast models like GFS and ECMWF, which project peaks in this range amid a strengthening high-pressure ridge over California. This synoptic pattern promotes subsidence warming and suppresses the typical marine layer and coastal stratus, pushing temperatures well above the March climatological average of 62°F. Recent 24-hour model updates show GFS trending slightly hotter toward 78°F while ECMWF favors 76°F, differentiating the leading bins; lower outcomes recede due to minimal support from cooler Euro analogs and historical coastal moderation. New forecast runs expected tonight could refine the peak hour maximum before resolution.
