Lowest temperature in San Francisco on Sep 18, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at San Francisco (CLISFO) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The Weather Company’s data is the sole authority for resolution, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary data 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. A “Final” status on weather.com/kalshi is for convenience only and does not guarantee data accuracy or exempt the market from potential adjustments due to errors.
