Description

This market tracks the highest daytime temperature recorded in Seattle on July 20, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which provides the maximum temperature reading for the location.

Kalshi

Resolution is based on the maximum temperature recorded at Seattle on July 20, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the NWS website for the Seattle office. The official data source is CLISEA from the NWS daily climate report for Seattle-Tacoma, WA. Temperature readings are divided into six ranges: 80°F or below, 81-82°F, 83-84°F, 85-86°F, 87-88°F, and 89°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
