This event tracks the lowest temperature recorded in Boston on a specific date, using official government data. Participants assess the likelihood of different temperature ranges based on historical trends and forecasts. The outcome depends solely on the official National Weather Service report for that day.
All markets resolve based on the minimum temperature recorded at Boston (Logan Airport), MA on August 11, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The official NWS report is the sole source for determining the outcome, and traders must use the latest version available after the date in question. Preliminary data from other services may differ due to rounding or conversion nuances, so only the official NWS report is binding. All markets are mutually exclusive and collectively exhaustive, meaning exactly one will resolve to Yes based on where the actual minimum temperature falls within these defined ranges.
