This market tracks the highest temperature recorded in San Francisco on July 12, 2026, using official National Weather Service data from San Francisco Airport. The outcome will be determined by the maximum temperature reading on that specific date.
Resolution is based on the maximum temperature recorded at San Francisco Airport on July 12, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, and 80°F or above. Each range corresponds to a distinct outcome. Official data must be obtained from the NWS Climatological Report accessed through the specified URL, selecting San Francisco Airport with Daily Climate Report. While preliminary NWS data and third-party weather services may provide guidance, the final determination uses only the official NWS Climatological Report (Daily) values. Traders should note that preliminary NWS reporting may involve rounding and conversion nuances that could affect interpretation.
