Description

This event tracks the lowest temperature recorded in Boston on a specific future date, using official government data. Participants assess whether temperature conditions will fall within certain predefined ranges based on verified meteorological reports.

Kalshi

All markets resolve based solely on the official minimum temperature recording for Boston (Logan Airport, MA) on July 26, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: below 48°F, 48-49°F, 50-51°F, 52-53°F, 54-55°F, or above 55°F. The National Weather Service's data is the definitive source, and traders must access the latest Daily Climate Report via the provided URL. Preliminary or third-party weather data should not be used for resolution, as official NWS reports may include rounding or conversion nuances that affect outcomes. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to "Yes" based on where the actual recorded minimum temperature falls within these defined brackets.
