This event tracks whether specific temperature thresholds will be reached in San Diego on a particular date, using an official weather data source. Participants can bet on the likelihood of different temperature ranges being met or exceeded. The outcome depends entirely on the accuracy and final reporting of weather measurements from the designated provider.
All markets resolve based on the maximum temperature recorded in San Diego (CLISAN) on October 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 79°F or below, 80-81°F, 82-83°F, 84-85°F, 86-87°F, or 88°F and above. The official data from The Weather Company is the sole determinant, and preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication, the Exchange may delay resolution until a corrected value is released or until the expiration date. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational and does not guarantee error-free data.
