Description

This event tracks the highest temperature reached in San Diego on a specific date in the future. It categorizes possible temperature outcomes into distinct ranges, each representing a different market outcome. The resolution depends on official weather data from a designated source.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on August 31, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded temperature falls within a specific range, the associated market resolves to Yes; otherwise, it resolves to No. All markets use The Weather Company as the sole authority for temperature data, with preliminary readings subject to potential rounding or conversion differences. Users should exercise caution when interpreting early data, as only the final official value determines the resolution. The secondary rules emphasize that while other weather services may offer guidance, they do not influence the official outcome.
