This event tracks whether Seattle will experience specific temperature ranges on a particular day in 2026. The outcome depends solely on official weather service data for that location and date, reflecting climate conditions rather than forecasts or estimates.
All markets resolve based on the maximum temperature recorded in Seattle on July 27, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: 75° or below, 76-77°, 78-79°, 80-81°, 82-83°, or above 83°F. The official NWS data, accessible via the provided URL under the 'Observed Weather' tab with the Daily Climate Report selected, is the sole determinant. Traders must use the latest reported data, noting that update frequencies may vary by city. Preliminary NWS data may include rounding or conversion nuances, so caution is advised when interpreting it. External sources like AccuWeather or Google Weather are informational only and do not affect resolution.
