This event tracks the peak temperature in Philadelphia on a specific summer day in 2026, using official government data as the definitive source. Participants assess the likelihood of different temperature ranges based on historical trends and seasonal forecasts. The outcome depends solely on the National Weather Service's official report for that date.
All markets resolve based exclusively on the highest temperature recorded at Philadelphia International Airport on July 29, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined: less than 79°F, 79-80°F, 81-82°F, 83-84°F, 85-86°F, and greater than 86°F. Regardless of preliminary or third-party weather data, the final market resolution hinges entirely on the NWS report, which may include rounding and conversion nuances that participants must account for when evaluating outcomes.
