This event tracks the highest temperature reached in Seattle on a specific date in the future, using official government data. Participants assess whether conditions will fall within certain temperature ranges based on verified meteorological reports.
All markets resolve based solely on the maximum temperature recorded in Seattle on August 3, 2026, as officially reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: below 75°F, 75-76°F, 77-78°F, 79-80°F, 81-82°F, or above 82°F. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. Preliminary or third-party data sources are not authoritative, and users should be aware of potential rounding or conversion nuances in NWS reporting. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to "Yes" based on where the actual temperature falls within these defined brackets.
