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 assess whether temperatures will fall within certain ranges based on official measurements.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on October 15, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that resolves 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 data is the sole authority, though participants may reference other sources for guidance. Preliminary data may differ from final figures due to rounding or conversion, so caution is advised. If the Exchange identifies a material error in the initial data release, it may delay resolution until a corrected version is published or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. A 'Final' status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
