Lowest temperature in Boston on Oct 21, 2026?

Kalshi

The event resolves based on the minimum temperature recorded at Boston's CLIBOS station on October 21, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range, with outcomes determined solely by The Weather Company's official data. All markets share identical secondary rules regarding data interpretation and error handling. Preliminary data may be subject to rounding or conversion differences, and participants should exercise caution when evaluating early readings. If the Exchange identifies a material error in the initial non-preliminary publication, it may delay expiration until a corrected revision is published or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The status of 'Final' on weather.com/kalshi is provided for convenience but does not guarantee data accuracy or exempt the market from these error-resolution procedures.
