Description

This event tracks the highest temperature 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 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 94°F or below, 95-96°F, 97-98°F, 99-100°F, 101-102°F, or above 102°F. The official data from The Weather Company is the sole determinant, and users should exercise caution with preliminary readings due to potential rounding or conversion differences. If a material error is identified in the initial publication, the Exchange may delay expiration until a corrected revision is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
