This event tracks the highest temperature recorded in San Francisco on a specific future date, using official government data. The outcome depends solely on the exact temperature measurement reported by the National Weather Service for that day.
All markets resolve based exclusively on the maximum temperature recorded at San Francisco Airport on July 24, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 67°F, 67-68°F, 69-70°F, 71-72°F, 73-74°F, or above 74°F. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may be referenced for guidance, only the NWS report determines resolution. Traders should be aware that NWS data may include rounding and conversion nuances, and reporting frequencies can vary between locations.
