Description

This event tracks the highest temperature reached in San Francisco on a specific date in the future. It categorizes possible temperature outcomes into ranges, each corresponding to a different resolution condition. The event uses a single authoritative source to determine the final result.

Kalshi

The event resolves based on the maximum temperature recorded at San Francisco (CLISFO) on August 19, 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; all other markets resolve to No. While other weather sources may provide similar data for reference, The Weather Company’s report is the exclusive authority for determining the final outcome. This structure ensures clarity and consistency in resolving the event, despite potential variations in temperature reporting across different services.
