Description

This event tracks the lowest temperature recorded in Boston on a specific date, using official government data as the sole source for verification. Participants assess whether the temperature will fall within certain ranges based on precise measurements from a designated weather station.

Kalshi

All markets resolve based solely on the minimum temperature recorded at Boston (Logan Airport), MA on July 30, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: 54° or below, 55-56°, 57-58°, 59-60°, 61-62°, or above 62°. The official NWS data must be accessed via the provided URL, with traders advised to use the latest available report and remain cautious about potential rounding or conversion nuances in preliminary data. No alternative weather sources are considered valid for resolution, regardless of apparent discrepancies. All outcomes depend entirely on the exact numerical value reported in the authoritative NWS document for that date and location.
