Description

This event tracks the highest temperature recorded in Boston on July 16, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with temperature ranges spanning from 84°F or below up to 93°F or above.

Kalshi

Resolution is based on the maximum temperature recorded at Boston on July 16, 2026, as reported by the National Weather Service's Climatological Report (Daily), accessible via the NWS BOX office climate data portal by selecting Boston (Logan Airport), MA. The official temperature measurement from this source is the sole determinant, superseding preliminary reports or alternative weather services. Traders should note that NWS preliminary data may be subject to rounding and conversion nuances, and the final daily report should be consulted for accurate resolution. Temperature ranges are divided into six distinct bands: 84°F or below, 85-86°F, 87-88°F, 89-90°F, 91-92°F, and 93°F or above.
