This event tracks the lowest temperature recorded in Boston on a specific date in the future, using official government data. Participants assess the likelihood of different temperature ranges based on historical trends and climate predictions. The outcome depends solely on the official National Weather Service report for that day.
All markets resolve based on the official minimum temperature recorded at Boston (Logan Airport), MA on July 27, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 48° or below, 49-50°, 51-52°, 53-54°, 55-56°, or 57° and above. The National Weather Service's report is the definitive source, and traders must use the latest version available after the reporting period. Preliminary data from other services may differ due to rounding or conversion nuances, so only the official NWS report determines the resolution. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to 'Yes' depending on where the actual temperature falls within these defined ranges.
