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 impacts of climate patterns on local weather conditions.
All markets resolve based on the maximum temperature recorded at San Diego's CLISAN station on September 24, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: below 78°F, 78-79°F, 80-81°F, 82-83°F, 84-85°F, or above 85°F. The Exchange holds expiration if a material error is identified in preliminary data, extending until a corrected value is published or the expiration date arrives. If no data remains available by the expiration date, markets resolve to the last fair price determined by Kalshi. While other weather services may show different values, The Weather Company's report is the sole authority for resolution.
