This event tracks the lowest temperature recorded in San Francisco on a specific future date, using official government data sources. Participants assess weather conditions based on historical trends and forecasts to determine the probable temperature range for that day.
All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport on August 8, 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 the Daily Climate Report for San Francisco Airport. The latest available version of the data should be used, acknowledging that update frequencies may vary by location. While third-party weather services may offer preliminary or estimated data, they are not authoritative; only the NWS report determines resolution. Traders must recognize that preliminary NWS data might contain rounding or conversion discrepancies, requiring careful interpretation. Each market corresponds to a specific temperature range: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The market whose defined range matches the official NWS minimum temperature will resolve as 'Yes,' with all others resolving as 'No.'
