This event tracks the highest temperature recorded in Boston on a specific date in the future, using official government data as the sole source for verification. Participants assess whether the temperature will fall within certain ranges based on historical trends and climate predictions.
The event resolves based on the maximum temperature recorded at Boston (Logan Airport), MA on July 29, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 67°F or below, 68–69°F, 70–71°F, 72–73°F, 74–75°F, or above 75°F. The official NWS data is the definitive source, and traders must use the latest version of the Daily Climate Report for Boston. Preliminary data from other services may differ due to rounding or conversion nuances, so caution is advised when interpreting such information. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to Yes depending on where the actual temperature falls within the defined ranges.
