This event tracks the highest temperature reached in San Francisco on a specific date in the future, using official government data. The outcome depends solely on the exact temperature recorded, with different ranges determining various results.
All markets resolve based exclusively on the maximum temperature recorded at San Francisco Airport on August 6, 2026, as reported in the National Weather Service's official Climatological Report (Daily). The report must be accessed via the provided URL after the date passes, using the latest available version. Temperatures are evaluated against specific ranges: below 72°F, 72-73°F, 74-75°F, 76-77°F, 78-79°F, or above 79°F. Traders should note that while third-party weather services may offer preliminary data, only the NWS report serves as the definitive source. Preliminary NWS data may contain rounding or conversion nuances, so caution is advised in interpreting early indications. All markets are mutually exclusive, with only one resolving to Yes based on where the actual temperature falls within these defined brackets.
