This event tracks the highest temperature reached in San Diego on a specific future date, using data from a designated weather provider. The outcome depends entirely on how warm it gets that day, with different markets covering various temperature ranges.
All markets resolve based on the maximum temperature recorded at San Diego (CLISAN) on October 12, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 67°F or below, 68-69°F, 70-71°F, 72-73°F, 74-75°F, or above 75°F. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending until a corrected version appears or the expiration date passes. If data remains unavailable by expiration, markets resolve at the last fair price determined by Kalshi. While other weather sources may show different values, only The Weather Company's official report determines outcomes. Preliminary readings may differ from final values due to rounding or conversion issues, so participants should exercise caution when interpreting early data.
