This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 24 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksfo This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Trader consensus assigns an 85.4% implied probability to a daily maximum of 70-71°F in San Francisco on August 24, driven by persistent marine-layer cooling from the Pacific and typical late-summer atmospheric patterns. NOAA forecast models and local observations showed onshore flow maintaining temperatures in the upper 60s to low 70s, with minimal offshore wind or subsidence to allow stronger warming. Historical climatology for August places average highs near 68-70°F, and no anomalous heat events or model runs deviated significantly from this baseline in the preceding 48 hours. Upcoming official National Weather Service verification data will confirm the exact maximum and resolve the market.
