This event tracks the lowest temperature recorded in San Francisco on a specific date, using official government data. The outcome depends on where the exact minimum temperature falls within predefined ranges, reflecting how precise weather measurements can influence real-world assessments.
The event determines the outcome based on the minimum temperature recorded in San Francisco on July 31, 2026, as reported by the National Weather Service's Climatological Report (Daily) for San Francisco Airport. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded minimum temperature falls within a specific range, that market resolves to Yes, with all others resolving to No. The official data source is critical; traders must refer to the NWS report linked in the rules, as preliminary or third-party data may differ due to rounding or conversion nuances. The final temperature value from the NWS report is definitive, and all participants must use the latest available version of the data after the date in question. The structure ensures that only one market can resolve to Yes, corresponding to the exact temperature range in which the official minimum falls.
