This market tracks the lowest temperature recorded in Houston on July 20, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for Houston-Hobby Airport, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at Houston-Hobby Airport on July 20, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 69°F or below, 70-71°F, 72-73°F, 74-75°F, 76-77°F, and 78°F or above. Each range corresponds to a separate market outcome. The official data source is accessed through the NWS website at the Houston office, selecting the Observed Weather tab and Houston-Hobby with Daily Climate Report. Traders should note that preliminary NWS data may contain rounding and conversion nuances, and the final official report takes precedence over other weather sources such as AccuWeather or Google Weather.
