Lowest temperature in San Francisco on Sep 15, 2026?

Kalshi

The event resolves based on the minimum temperature recorded in San Francisco (CLISFO) on September 15, 2026, as reported by The Weather Company. Six distinct temperature range markets exist, each corresponding to a specific interval: 51° or below, 52-53°, 54-55°, 56-57°, 58-59°, and 60° or above. The market that matches the actual recorded minimum temperature range will resolve to 'Yes,' with all others resolving to 'No.' All markets share common secondary rules regarding data verification and error handling. The Weather Company’s reported value is the sole authority, even if other sources show different data. Preliminary readings may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial non-preliminary data, it may delay expiration until a corrected version is published or until the expiration date arrives, whichever comes first. Should no data remain available by the expiration date, all markets resolve to the last fair price determined by Kalshi. A 'Final' status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt the market from these error-resolution procedures.
