This event tracks the highest temperature reached in Phoenix on a specific date in the future, using official government data. Participants assess whether conditions will lead to certain temperature ranges being met or exceeded on that day.
All markets resolve based solely on the maximum temperature recorded in Phoenix, AZ on August 11, 2026, as reported by the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 101°F, 101-102°F, 103-104°F, 105-106°F, 107-108°F, or above 108°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 offer guidance, only the NWS report determines resolution. Users should be aware that NWS data may include rounding and conversion nuances, and reports across cities may update at different frequencies. The URL provided in the secondary rules directs traders to the correct data source, where the "Observed Weather" tab and "Phoenix, AZ" location with "Daily Climate Report" selected will display the relevant information.
