Description

This event tracks the highest temperature reached in Seattle on a specific date in 2026. Outcomes depend on exact temperature ranges, with different markets covering various intervals from mild to extreme heat. The resolution relies on official government weather data for accuracy.

Kalshi

All markets resolve based on the maximum temperature recorded in Seattle on August 11, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 75° or below, 76-77°, 78-79°, 80-81°, 82-83°, or above 83° Fahrenheit. The National Weather Service's data is the sole authority for determining outcomes, and traders must use the latest available report for the date. Preliminary data may contain rounding or conversion nuances, so caution is advised. Secondary instructions provide the exact URL for accessing the official Seattle-Tacoma, WA daily climate report, emphasizing that other weather sources are informational only and not binding. All markets share these core data sourcing and validation requirements.
