Description

This event tracks the lowest temperature recorded in San Diego on a specific date in the future, using data from a designated weather provider. Participants can speculate on whether the temperature will fall within certain degree ranges, with outcomes determined by official readings.

Kalshi

The event resolves based on the minimum temperature recorded in San Diego (CLISAN) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 58° or below, 59-60°, 61-62°, 63-64°, 65-66°, or above 66°. The official data source is The Weather Company, and all participants must rely on its final reported value, regardless of other weather services. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version 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 status of "Final" on weather.com/kalshi is for convenience only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
