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 the likelihood of different temperature ranges based on historical patterns and forecasts.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at Boston (Logan Airport), MA on July 31, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The exact temperature value from the NWS report determines the resolving market, with no consideration for preliminary or third-party data sources. Traders must rely exclusively on the final, officially published NWS data for the specified date, noting that reporting nuances and rounding conventions may affect interpretations of borderline values.
