This event tracks the highest temperature recorded in Boston on a specific date in 2026. Participants assess whether conditions will reach certain temperature thresholds based on official weather service data. Outcomes depend solely on the maximum temperature measured at a designated location on that day.
All markets resolve based on the maximum temperature recorded at Boston (Logan Airport), MA on August 12, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 82°F or below, 83-84°F, 85-86°F, 87-88°F, 89-90°F, or above 90°F. The official data source must be accessed via the provided NWS URL, and traders should use the latest available report for the date. Preliminary data from other services may differ due to rounding or conversion differences, so only the NWS report serves as the binding authority for resolution. All markets are mutually exclusive and collectively exhaustive within the defined temperature bands.
