Description

This event tracks the expected low temperature in Boston on a specific future date, helping participants assess climate conditions for planning or speculative purposes. The outcome depends solely on official weather data from a designated source, ensuring consistency despite variations in public weather reports.

Kalshi

The event determines the resolution based on the minimum temperature recorded at Boston’s CLIBOS station on August 17, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the recorded low falls within a given range, that market resolves as 'Yes,' with all others resolving as 'No.' The Weather Company’s data serves as the exclusive, binding authority, overriding any conflicting or alternative weather reports. This structure ensures a clear, objective method for determining the event’s outcome based on precise temperature thresholds.
