This event tracks the highest temperature recorded in San Francisco on a specific date in the future, 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 31, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 71°F, 71-72°F, 73-74°F, 75-76°F, 77-78°F, or above 78°F. The official NWS report is the definitive source, and traders must use the latest version available after the date. Preliminary data from other services may differ due to rounding or conversion nuances, so only the final NWS figure determines resolution. All markets are mutually exclusive and collectively exhaustive for possible outcomes within these defined ranges.
