This event tracks the lowest temperature recorded in Seattle on a specific date, using official government data as the sole source for verification. Participants assess whether conditions will fall within certain temperature ranges based on authoritative meteorological reports.
All markets resolve based solely on the official minimum temperature recorded in Seattle on August 10, 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 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or above 57°F. The resolving authority will access the latest official data from the NWS website, following the navigation path specified in the secondary rules. Traders must recognize that preliminary readings may contain rounding or conversion nuances, and only the final official report determines outcomes. External weather services may offer guidance but hold no resolving power. All participants acknowledge that reporting frequencies vary across locations and should use the most current official data available at resolution time.
