This event tracks the lowest temperature recorded in San Francisco on a specific future date, using official government data sources. The outcome depends entirely on the exact numerical minimum temperature reported for that day, with different ranges determining distinct results.
All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport on July 28, 2026, as reported in the National Weather Service's Climatological Report (Daily). The report must be accessed via the provided URL, navigating to the 'Observed Weather' tab and selecting 'San Francisco Airport' with 'Daily Climate Report'. The latest available version of the data should be used, acknowledging that update frequencies may vary between locations. The NWS report is the definitive source; other weather services may offer guidance but are not authoritative. Traders must be aware that preliminary NWS data could contain rounding or conversion nuances, requiring careful interpretation. Each market corresponds to a specific temperature range: below 53°F, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The market resolving to 'Yes' is the one whose defined range matches the officially reported minimum temperature.
