Description

This event tracks the lowest temperature recorded in Boston on a specific future date, using official government data sources. Participants assess the likelihood of different temperature ranges based on historical trends and climate predictions. The outcome depends solely on the official National Weather Service report for that day.

Kalshi

All markets resolve based exclusively on the official minimum temperature recorded at Boston (Logan Airport), MA, as reported in the National Weather Service's Climatological Report (Daily) for July 24, 2026. Each market corresponds to a specific temperature range: 48°F or below, 49-50°F, 51-52°F, 53-54°F, 55-56°F, or above 56°F. The secondary rules emphasize that while third-party weather services may offer preliminary data, only the NWS report serves as the definitive source. Traders must access the latest version of the data from the provided NWS URL after the event date, noting that reporting schedules and potential rounding conventions could affect interpretations of preliminary data. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to 'Yes' based on where the actual recorded minimum falls within these defined ranges.
