This market tracks the highest temperature recorded in Washington DC on July 15, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, which provides the authoritative maximum temperature measurement for Washington-National Airport.
Resolution is based on the maximum temperature recorded at Washington DC on July 15, 2026, as reported in the National Weather Service's Climatological Report (Daily), accessible via the CLIDCA database. The official data source is the NWS Climatological Report rather than preliminary reports or third-party weather services. Temperature measurements are divided into six ranges: below 98°F, 98-99°F, 100-101°F, 102-103°F, 104-105°F, and 106°F or above. Each range corresponds to a distinct market outcome. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances, and should rely on the final version of the Climatological Report for accurate resolution.
