This event tracks the lowest temperature recorded in Washington DC on a specific future date, using official government data sources. The outcome depends entirely on the exact temperature reading reported after the event occurs, making it a straightforward test of weather conditions against predefined thresholds.
All markets resolve based solely on the official minimum temperature recorded at Washington DC on July 24, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Washington-National. Traders must access the data via the provided NWS URL, selecting the "Observed Weather" tab and using the Daily Climate Report for the exact date. The latest available report should be used, acknowledging that update frequencies may vary between locations. While third-party weather services may offer preliminary or estimated values, only the NWS report serves as the binding authority for resolution. Traders are cautioned that preliminary NWS data may contain rounding or conversion discrepancies, and final certification should rely on the authoritative daily report once published.
