Description

This event tracks the lowest temperature recorded in Seattle on a specific date, using official government data as the sole source for verification. Participants assess whether conditions will fall within certain temperature bands based on historical trends and seasonal patterns.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at Seattle-Tacoma, WA on July 31, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: below 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or above 57°F. The NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may provide guidance, only the NWS report determines resolution. Users should be aware that NWS data may include rounding and conversion nuances, and reports across cities may update at different frequencies, requiring careful verification of the official Seattle-Tacoma report.
