This market tracks the lowest temperature recorded in Boston on July 15, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Boston Logan Airport, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at Boston Logan Airport on July 15, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Boston office climate portal under the Observed Weather tab. Six distinct temperature ranges partition the possible outcomes: 70°F or below, 71-72°F, 73-74°F, 75-76°F, 77-78°F, and 79°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded minimum falls within that band. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be consulted for resolution purposes rather than real-time weather services.
