This event tracks the lowest temperature recorded in Seattle on July 17, 2026. The outcome will be determined by the official National Weather Service Climatological Report for that date, accessed through their daily climate data portal for Seattle-Tacoma.
Resolution is based on the minimum temperature recorded at Seattle-Tacoma on July 17, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Western Region Headquarters climate portal by selecting the "Observed Weather" tab, then "Seattle-Tacoma, WA" with Daily Climate Report. The reported minimum temperature determines which outcome resolves affirmatively: below 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or above 57°F. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) takes precedence over other weather sources such as AccuWeather or Google Weather.
