Kalshi
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 official temperature reading reported by The Weather Company for that day.
All markets resolve based solely on the minimum temperature recorded at San Diego (CLISAN) on September 20, 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 above 67°F. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending the evaluation until a corrected value is released or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve at the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, so participants should exercise caution when interpreting early data. The "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential resolution adjustments.
