This event tracks the lowest temperature recorded in San Francisco on a specific future date, using official government data sources. Participants assess probable weather conditions based on historical trends and forecasts, with outcomes determined solely by verified measurements from the National Weather Service.
All markets resolve based exclusively on the official minimum temperature recorded at San Francisco Airport on August 13, 2026, as reported in the National Weather Service's Climatological Report (Daily). The outcome is determined by comparing this verified temperature against predefined ranges: below 53°F, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. Traders must rely on the authoritative NWS data linked in the rules, as preliminary or third-party weather reports may differ due to rounding, conversion, or timing variances. The latest available NWS report for the specified date will be used as the definitive source, with all markets resolving according to which temperature range encompasses the officially recorded low.
