This event tracks the highest temperature recorded in Houston on a specific date in the future, using official government data as the sole source for verification. Participants assess weather conditions and historical trends to predict temperature ranges.
All markets resolve based solely on the maximum temperature recorded at Houston-Hobby, TX on July 30, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: 95°F or below, 96-97°F, 98-99°F, 100-101°F, 102-103°F, or above 103°F. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may be referenced for guidance, only the NWS report determines the outcome. Traders should be aware that NWS data may include rounding and conversion nuances, and reports across cities may update at different frequencies, requiring careful verification of the final published figures.
