This event tracks the lowest temperature recorded in Boston on a specific future date, using official government data sources. 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 exclusively on the minimum temperature recorded at Boston (Logan Airport), MA, as reported in the National Weather Service's Climatological Report (Daily) for July 25, 2026. Each market corresponds to a specific temperature range: 47° or below, 48-49°, 50-51°, 52-53°, 54-55°, or 56° and above. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may offer guidance, only the NWS report determines resolution. Traders should be aware that NWS data may include rounding and conversion nuances, and reports across cities may update at different frequencies, requiring careful verification of the final data.
