Description

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

Kalshi

All markets resolve based solely on the official minimum temperature recorded at Boston (Logan Airport), MA, as reported in the National Weather Service's Climatological Report (Daily) for July 29, 2026. Each market corresponds to a specific temperature range: 59° or below, 60-61°, 62-63°, 64-65°, 66-67°, or 68° and above. The exact temperature value determines which market resolves to 'Yes,' with all others resolving to 'No.' Traders must reference the official NWS data source provided, as preliminary or third-party weather reports are not authoritative. It is important to note that NWS data may undergo revisions, and participants should use the latest available report for the date in question. Rounding and conversion methodologies inherent in NWS reporting may impact interpretations of borderline cases, so caution is advised when evaluating near-threshold temperatures.
