Description

This market tracks the lowest temperature recorded in Boston on July 19, 2026. The outcome is determined by the minimum temperature reading from the National Weather Service's official daily climatological report for Boston Logan Airport, which serves as the authoritative source for weather data in the region.

Kalshi

Resolution is based on the minimum temperature recorded at Boston (Logan Airport) on July 19, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS website by navigating to the Observed Weather tab and selecting Boston (Logan Airport), MA with Daily Climate Report. The temperature is divided into six ranges: 56°F or below, 57-58°F, 59-60°F, 61-62°F, 63-64°F, and 65°F or above. Each range corresponds to a separate outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) value takes precedence over other weather sources such as AccuWeather or Google Weather.
