This market tracks the highest temperature recorded in Seattle on July 21, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Seattle-Tacoma, which records the maximum temperature reached during that calendar day.
Resolution is based on the maximum temperature recorded at Seattle-Tacoma on July 21, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS website under the Seattle office, Observed Weather section, selecting Seattle-Tacoma, WA with Daily Climate Report. The maximum temperature determines which outcome resolves affirmatively: 87°F or below, 88-89°F, 90-91°F, 92-93°F, 94-95°F, or 96°F and above. 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 rather than preliminary readings or third-party weather services.
