This event tracks the highest temperature reached in San Diego on a specific date in the future, using data from a designated weather provider. Participants can speculate on whether temperatures will fall within certain ranges or exceed specific thresholds. The outcome depends solely on the official temperature recording from the chosen source.
The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on September 18, 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. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets will 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 error-free data.
