Description

This event tracks the lowest temperature recorded in Seattle on a specific date in the future, using official government data as the sole source for verification. Participants assess the likelihood of different temperature ranges based on historical patterns and seasonal forecasts.

Kalshi

All markets resolve based solely on the official minimum temperature recorded in Seattle on August 12, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: 51°F or below, 52-53°F, 54-55°F, 56-57°F, 58-59°F, or 60°F and above. The exact temperature value from the NWS report determines the resolving market, with no consideration given to preliminary or third-party data sources. Traders must rely on the final, official NWS data release for the date, noting that reporting schedules may vary and preliminary figures could be subject to revision. Rounding and conversion methodologies inherent in NWS reporting may impact borderline cases, requiring careful interpretation of the final published figures.
