This event tracks the lowest temperature recorded in San Diego on a specific future date, using data from a designated weather provider. The outcome depends entirely on the exact temperature reading reported for that day, with different markets covering various temperature ranges.
All markets resolve based on the minimum temperature recorded at San Diego (CLISAN) on October 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 59°F or below, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or 68°F and above. The Exchange uses The Weather Company's official reporting as the sole determinant, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if it identifies a material error in the initial publication. If no valid data remains available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee error-free data.
