Highest temperature in Seattle on Sep 19, 2026?

Kalshi

All markets resolve based on the maximum temperature recorded in Seattle (CLISEA) on September 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 69°F or below, 70-71°F, 72-73°F, 74-75°F, 76-77°F, or 78°F and above. The official data from The Weather Company is the sole determinant, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting it. If the Exchange identifies a material error in the initial non-preliminary 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 expiration date, all markets will resolve to the last fair price determined by Kalshi. The “Final” status on weather.com/kalshi is for convenience only and does not guarantee data accuracy or exempt markets from potential revisions under these rules.
