Lowest temperature in Seattle on Sep 21, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at Seattle (CLISEA) on September 21, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 45° or below, 46-47°, 48-49°, 50-51°, 52-53°, or above 53°. The official data source is The Weather Company, and while other weather services may show similar data, they do not affect the resolution. Preliminary data may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released 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 "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exemption from these error-resolution procedures.
