This market tracks the lowest temperature recorded in Seattle on July 22, 2026. The outcome will be determined by the National Weather Service's official daily climatological report for Seattle-Tacoma, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at Seattle-Tacoma on July 22, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website by navigating to the Observed Weather tab and selecting Seattle-Tacoma, WA with Daily Climate Report. The reported minimum temperature determines which temperature range outcome resolves affirmatively. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution. While other weather sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) serves as the authoritative source for final resolution.
