This event tracks the highest temperature recorded in Boston on July 22, 2026. The actual temperature will be measured and reported by the National Weather Service at Boston Logan Airport, with resolution determined by their official Climatological Report (Daily).
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.
