Description

This event tracks the highest temperature recorded in Seattle on a specific date in 2026. Outcomes depend on how the temperature compares to predefined ranges, using official government data as the sole source for verification.

Kalshi

All markets resolve based on the maximum temperature recorded in Seattle on August 13, 2026, as officially reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: 77°F or below, 78–79°F, 80–81°F, 82–83°F, 84–85°F, or above 85°F. The official NWS report is the definitive source, and traders must use the latest version available via the provided URL. Preliminary or third-party data sources are not valid for resolution. Traders should be aware that NWS data may include rounding or conversion nuances, and reports are updated at varying frequencies across locations.
