Description

This event tracks whether specific temperature thresholds will be reached in San Diego on a particular date in 2026. The outcome depends entirely on official weather data from a designated source, with specific ranges defining success for each market.

Kalshi

The event determines outcomes based on the maximum temperature recorded in San Diego (CLISAN) on September 8, 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 its specified range. The lowest market triggers if temperatures are 83°F or below, while subsequent markets activate for incremental ranges up to 91°F. The highest market resolves positively if temperatures exceed 91°F. All markets share identical secondary rules emphasizing that The Weather Company’s data is the sole authority, despite potential discrepancies with other weather services. Preliminary data may undergo revisions, and the exchange retains discretion to delay resolution for material errors or unresolved data, defaulting to the last fair price if necessary. The "Final" status on The Weather Company’s platform is informational and does not override these resolution protocols.
