Description

This event tracks the lowest temperature that will be recorded in San Francisco on a specific future date. The outcome depends on how cold it gets during that night, with different temperature ranges determining the result. The official data source for temperature verification is The Weather Company.

Kalshi

The event resolves based on the minimum temperature recorded at San Francisco (CLISFO) on August 21, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature falls within a specific range, that market resolves to Yes. All markets are mutually exclusive and collectively exhaustive, ensuring exactly one outcome will occur based on where the actual temperature falls within the defined brackets. The Weather Company serves as the sole authoritative source for temperature data, and all participants must accept its reported values as final for resolution purposes, regardless of discrepancies found in other weather services.
