Description

This event tracks the highest temperature reached in Seattle on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for a particular day, reflecting real-world interest in weather forecasting and climate patterns.

Kalshi

The event resolves based on the maximum temperature recorded at Seattle (CLISEA) on August 17, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and methodology, ensuring consistency in evaluation. While other weather services may provide similar data, The Weather Company’s report is the sole authority for determining the final outcome.
