The event resolves based on the maximum temperature recorded at Boston (Logan Airport, MA) on July 28, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six temperature ranges are defined: 76°F or below, 77-78°F, 79-80°F, 81-82°F, 83-84°F, and 85°F or above. If the recorded temperature falls within any of these ranges, the corresponding market resolves to Yes.
