This market tracks the overnight low temperature in New York City on July 17, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which records the minimum temperature reached during the 24-hour observation period at Central Park.
Resolution is based on the minimum temperature recorded at New York City on July 17, 2026, as reported in the National Weather Service's Climatological Report (Daily) for the New York office. The official data source is accessed via the NWS New York regional office climate portal, selecting the "Observed Weather" tab and Central Park NY location with Daily Climate Report. The minimum temperature is divided into six distinct ranges: 66°F or below, 67-68°F, 69-70°F, 71-72°F, 73-74°F, and 75°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that bracket. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
