This event tracks the lowest temperature recorded in Seattle on a specific date, using official government data. It helps participants assess historical climate patterns and predict future weather conditions based on reliable sources.
All markets resolve based solely on the official minimum temperature recorded in Seattle on July 30, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: below 48°F, 48–49°F, 50–51°F, 52–53°F, 54–55°F, or above 55°F. The data must be retrieved from the NWS website after the date passes, using the 'Observed Weather' tab and Daily Climate Report function. Traders should rely exclusively on this source, as other weather services may differ. Preliminary reports may contain rounding or conversion discrepancies, so final resolution uses the latest official data once available. All markets are mutually exclusive and collectively exhaustive, ensuring exactly one will resolve as 'Yes' based on where the actual temperature falls within these defined brackets.
