Trader consensus on Polymarket splits nearly evenly between an unusually cool high of 45°F or below (50%) and a mild 64°F or higher (50%), reflecting high uncertainty in the persistence of San Francisco's coastal marine layer amid variable spring onshore flow. NOAA's GFS and ECMWF ensembles currently cluster downtown highs around 59–62°F for April 14, but model divergences on stratus burn-off timing and low-level cool air advection create the bimodal sentiment: prolonged fog under a strong inversion could cap peaks near record-low April highs (historically as low as 49°F), while quicker clearing and subtle ridge amplification offshore would push into climatological norms near 63°F. Following recent showers through April 12, watch NWS Bay Area updates for 00Z/12Z runs resolving inversion depth.

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.
