Description

This event tracks the highest temperature reached in San Diego on a specific future date, using a trusted weather data provider as the official source. Participants can assess various temperature ranges to determine the outcome based on actual recorded conditions.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on August 29, 2026, as reported by The Weather Company. Six distinct temperature ranges define possible outcomes, each triggering a 'Yes' resolution for the corresponding market if the recorded high falls within that range. The Weather Company serves as the sole authoritative source for temperature data, with all participants advised that preliminary readings may vary due to rounding or conversion differences, and the final reported value takes precedence. Consistency across all markets is ensured by using identical data sources and interpretation rules, eliminating ambiguity from disparate weather service reports.
