Description

This event tracks whether Boston will experience specific temperature ranges on a particular day in the future. The outcome depends solely on the official weather data recorded at a designated location. Participants can assess historical climate patterns and seasonal forecasts to gauge likelihood.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's CLIBOS station on September 23, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: below 60°F, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or above 67°F. The Weather Company’s data is the definitive source, though users should exercise caution with preliminary readings due to potential rounding or conversion discrepancies. If the Exchange identifies a material error in the initial data publication, it may delay expiration until a corrected version is released or until the expiration date itself—whichever comes first. Should no data remain available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not exempt the data from potential error correction.
