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 that exact day. The outcome depends solely on the official temperature recording from the chosen weather service.

Kalshi

The event resolves based on the maximum temperature recorded at Seattle (CLISEA) on August 31, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes: less than 71°F, 71–72°F, 73–74°F, 75–76°F, 77–78°F, or greater than 78°F. The official determination uses The Weather Company’s final reported value, regardless of preliminary readings or data from other services. Participants should note that preliminary data may vary due to rounding or conversion differences, and only the authoritative source’s confirmed figure decides the market outcome.
