Kalshi

Resolution is determined by the maximum temperature recorded at Boston Logan Airport on July 22, 2026, as reported in the National Weather Service's Climatological Report (Daily), accessible via the NWS Boston office climate data portal. The official temperature reading is divided into six temperature bands: 79°F or below, 80-81°F, 82-83°F, 84-85°F, 86-87°F, and 88°F or above. Each band corresponds to a distinct market outcome. Traders should rely exclusively on the NWS Climatological Report (Daily) as the authoritative source, as preliminary NWS data and third-party weather services may contain rounding or conversion differences. The latest available data for the specified date should be used for resolution.
