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 28 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 sentiment for San Francisco's highest temperature on March 28 centers on NOAA's short-range forecasts indicating a peak near 68-72°F under a strengthening subtropical high-pressure ridge, elevating 74°F or higher odds to 28.5% despite competition from 66-73°F bins at 19.5-21.5%. Differentiating factors include marine layer persistence—persistent westerly sea breezes and coastal stratus typically cap highs at 64-67°F, as seen in 70% of recent March days, while northerly winds or ridge-induced subsidence could clear skies for 72°F+ outliers, akin to 2023's warm anomaly. Ensemble models show 2-4°F spread, with afternoon mixing depth key; monitor 12z GFS/ECMWF updates for shifts before resolution.
