This event tracks the peak temperature in San Francisco on a specific date in the future, using official government data as the sole source for verification. The outcome depends entirely on how high the temperature climbs on that day, with different ranges determining various results.
All markets resolve based solely on the maximum temperature recorded at San Francisco Airport on August 2, 2026, as reported in the National Weather Service's official 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 the exact date. The latest available version of the data should be used, acknowledging that update frequencies may vary between locations. While external 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 nuances, requiring careful interpretation until the official report is finalized. Each market corresponds to a specific temperature range or threshold, with overlapping ranges clearly defined to ensure unambiguous outcomes.
