Description

This event tracks the highest temperature reached in Seattle on a specific date in the future. It uses a single authoritative weather source to determine the outcome, ensuring consistency despite variations in other weather reports. The event is designed to test predictive abilities regarding weather conditions on that particular day.

Kalshi

The event determines its outcome based on the maximum temperature recorded at Seattle (CLISEA) on August 26, 2026, as reported by The Weather Company. Six distinct temperature ranges define possible resolutions: less than 75°F, 75-76°F, 77-78°F, 79-80°F, 81-82°F, or greater than 82°F. Each range corresponds to a specific market outcome resolving to Yes if the recorded temperature falls within that range. All secondary rules emphasize that while other weather sources may provide similar data, The Weather Company’s report is the sole authority for resolution. Participants should exercise caution with preliminary data, as rounding and conversion differences may occur before the final official value is published.
