Description

This event tracks whether specific temperature thresholds will be reached in San Diego on a particular day in the future. Outcomes depend solely on official weather data from a designated source, with mechanisms to address potential data discrepancies.

Kalshi

All markets resolve based on the maximum temperature recorded at San Diego (CLISAN) on September 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 81°F or below, 82-83°F, 84-85°F, 86-87°F, 88-89°F, or 90°F and above. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending the period until a corrected value is released or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by the Exchange. The 'Final' status on The Weather Company's platform is informational and does not override these resolution procedures.
