This event tracks the lowest temperature recorded in Boston on July 17, 2026. The outcome will be determined by the official National Weather Service Climatological Report for Boston Logan Airport, MA, which records the minimum daily temperature.
Resolution is based on the minimum temperature recorded at Boston Logan Airport, MA on July 17, 2026, as reported in the National Weather Service's Climatological Report (Daily). The event is divided into six temperature bands: 55°F or below, 56-57°F, 58-59°F, 60-61°F, 62-63°F, and 64°F or above. Each band corresponds to a separate market outcome that resolves to Yes if the recorded minimum temperature falls within that range. Official data must be obtained from the NWS Climatological Report accessed through the Boston Weather Forecast Office website, specifically from the Boston Logan Airport, MA location with Daily Climate Report selected. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS report takes precedence over other weather sources.
