Description

This event tracks the highest temperature reached in San Diego on a specific future date, using data from a designated weather authority. Participants can speculate on whether temperatures will fall within certain ranges or exceed a specific threshold. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event resolves based on the maximum temperature recorded in San Diego (CLISAN) on August 20, 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 share the same data source and date, ensuring consistency in evaluation. While other weather services may show different values, The Weather Company’s report is the sole authority for determining the final outcome. This structure allows participants to assess the likelihood of various temperature scenarios for the specified day.
