This event tracks the lowest nighttime temperature in San Antonio on a specific date, using official government data. Participants assess how cool the evening will be based on historical trends and forecasts. The outcome depends solely on the official temperature report from the National Weather Service.
All markets resolve based exclusively on the minimum temperature recorded in San Antonio, Texas, on August 13, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 71°F, 71-72°F, 73-74°F, 75-76°F, 77-78°F, or above 78°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 resolution. Traders should be aware that NWS data may include rounding and conversion nuances, and reporting frequencies can vary, requiring careful verification of the final report.
