Description

This event tracks the daytime high temperature in Seattle on July 18, 2026. The outcome will be determined by the National Weather Service's official daily climatological report for Seattle-Tacoma, which records the maximum temperature reached during that calendar day.

Kalshi

Resolution is based on the maximum temperature recorded at Seattle-Tacoma on July 18, 2026, according to the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS website by navigating to the Observed Weather tab and selecting Seattle-Tacoma, WA with Daily Climate Report. Temperature ranges are divided into six bands: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, and 82°F or above. Each band corresponds to a separate outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) is the authoritative source, not preliminary reports or third-party weather services.
