This event tracks whether specific temperature thresholds will be reached in San Diego on a particular day in the future. Outcomes depend entirely on official weather data from a designated source, reflecting potential climate conditions for planning and risk assessment.
All markets resolve based on the maximum temperature recorded at San Diego (CLISAN) on September 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, or above 81°F. 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, so users should exercise caution. If the Exchange identifies a material error in the initial 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 and does not guarantee data accuracy or exempt markets from potential revisions.
