This market tracks the lowest overnight temperature recorded in Houston on July 22, 2026. The outcome is determined by the official National Weather Service daily climatological report for the Houston area, which provides the minimum temperature for that specific date.
Resolution is based on the minimum temperature recorded at Houston-Hobby on July 22, 2026, as reported in the National Weather Service's Climatological Report (Daily) accessible via the Houston NWS office. The official data source is the NWS Daily Climate Report for Houston-Hobby, TX, which can be accessed through the specified NWS regional office website. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS report is the authoritative source for resolution. While other weather services may provide reference data, only the NWS Climatological Report (Daily) determines the outcome.
