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 3 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 favors a high of 72°F or higher in San Francisco at 67.5% implied probability, driven by the latest National Weather Service forecasts indicating clear skies and rapid burn-off of the shallow marine layer under a strengthening upper-level ridge. After record-warm March temperatures—highlighted by a 73°F high at San Francisco International Airport (SFO) on March 31—and a brief cool snap with light rain limiting April 1-2 highs to 63°F, model ensembles now project enhanced subsidence warming and light onshore winds, allowing greater surface heating. Historical April averages hover around 63°F, but analogous sunny setups often exceed 70°F; persistent coastal stratus remains the key uncertainty that could cap outcomes at 70-71°F (25.5%). Real-time SFO observations will track progress toward resolution.
