Lowest temperature in Seattle on Oct 18, 2026?

Kalshi

All markets resolve based solely on the minimum temperature recorded at Seattle (CLISEA) on October 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 38°F or below, 39-40°F, 41-42°F, 43-44°F, 45-46°F, or above 46°F. The Weather Company's official report is definitive, even if other sources show different values. 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 report before expiration, it may delay resolution until a corrected version is published or until the expiration date. If no valid data exists by expiration, markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee error-free data.
