This market tracks the highest temperature recorded in Houston on July 19, 2026. The outcome is determined by the maximum temperature reading from the National Weather Service's official daily climatological report for that date.
Resolution is based on the maximum temperature recorded at Houston-Hobby, TX on July 19, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab for Houston-Hobby. Temperature ranges are divided into six bands: 93°F or below, 94-95°F, 96-97°F, 98-99°F, 100-101°F, and 102°F or above. Each band 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 report should be used for resolution rather than real-time or third-party weather services.
