Description

This event tracks whether specific temperature thresholds will be reached in San Diego on a particular date in 2026. Outcomes depend entirely on official weather data from a designated source, with markets resolving based on exact temperature ranges.

Kalshi

All markets resolve based on the maximum temperature recorded in San Diego (CLISAN) on October 17, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 85° or below, 86-87°, 88-89°, 90-91°, 92-93°, or above 93°F. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending until a corrected value is released or the expiration date passes. If data remains unavailable by expiration, markets resolve at 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.
