Description

This event tracks the lowest temperature recorded in San Diego on a specific future date, using data from a designated weather provider. Participants can assess various temperature ranges to predict how cold it might get during that night.

Kalshi

The event resolves based on the minimum temperature recorded in San Diego (CLISAN) on October 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 61° or below, 62-63°, 64-65°, 66-67°, 68-69°, or 70° and above. The official data source is The Weather Company, and while other weather services may show similar information, they do not determine the outcome. Preliminary data may be subject to rounding or conversion differences, so users should exercise caution. If a material error is identified in the initial publication, the exchange reserves the right to delay expiration until an accurate revision is issued or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by the exchange. The status of 'Final' on The Weather Company's platform is for convenience and does not guarantee data accuracy or exempt the event from potential adjustments due to errors.
