New York City’s weather on August 21, 2026 will be evaluated through six temperature thresholds, with each range dictating a unique market resolution using official data.
Each market’s outcome is tied to the maximum temperature recorded at New York City (CLINYC) on August 21, 2026, per The Weather Company. The markets are segmented into six ranges: 76° or below, 77° to 78°, 79° to 80°, 81° to 82°, 83° to 84°, and 85° or above. The secondary rule stresses that The Weather Company’s data is the definitive source, despite the existence of other weather services that might be used for reference.
