Description

This event tracks the lowest temperature recorded in Boston on a specific date, using official government data. Participants assess weather conditions and historical trends to predict the outcome.

Kalshi

The event resolves based on the minimum temperature recorded in Boston on August 3, 2026, as officially reported by the National Weather Service's Climatological Report (Daily) for Boston (Logan Airport), MA. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded minimum temperature falls within a specific range, the associated market resolves to Yes; otherwise, it resolves to No. All participants must refer exclusively to the official NWS data linked in the rules, as preliminary or third-party weather reports may differ due to rounding, conversion, or reporting nuances. The most recent version of the NWS Daily Climate Report for the specified date must be used to determine the final outcome. Traders should be cautious when interpreting early or unofficial data, as official NWS figures are the sole basis for resolution.
