Description

This event tracks the highest temperature recorded in San Diego on a specific date in the future, using data from a designated weather provider. Participants can assess various temperature ranges to determine possible outcomes based on climatological patterns and historical trends.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on September 26, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded temperature falls within that range. All markets share identical secondary rules regarding data verification and error handling. The Weather Company’s official reporting serves as the sole source for resolution, with preliminary data subject to revision. If a material error is identified before publication of a corrected value, the expiration may be delayed until a non-materially-erroneous revision is issued or the expiration date passes. Should no data remain available by the expiration date, markets resolve to the last fair price determined by the exchange. The 'Final' status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt markets from potential revisions under these rules.
