Description

This event tracks the highest temperature that will be recorded in San Diego on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on October 30, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 68° or below, 69-70°, 71-72°, 73-74°, 75-76°, or above 76°. The official data from The Weather Company is the sole determinant, and users should be cautious with preliminary readings due to potential rounding or conversion differences. If a material error is identified in the initial publication, the exchange may delay resolution until a corrected version is released or until the expiration date. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
