Description

This event tracks whether specific temperature thresholds will be reached in San Francisco on a particular day in the future. The outcome depends entirely on official weather data from a designated source, reflecting climate conditions rather than predictions or models.

Kalshi

All markets resolve based on the maximum temperature recorded at San Francisco (CLISFO) on October 30, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 61° or below, 62-63°, 64-65°, 66-67°, 68-69°, or 70° and above. The official data from The Weather Company is the sole determinant, even if other weather services report different values. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If no valid data is available by the expiration date, markets will resolve to the last fair price determined by the Exchange. The "Final" status on The Weather Company’s platform is informational and does not guarantee data accuracy or exempt markets from potential revisions.
