Description

This event tracks the highest temperature recorded in Seattle on a specific date in the future, using official government data sources. Participants assess whether the temperature will fall within certain ranges based on verified meteorological reports.

Kalshi

All markets resolve based on the maximum temperature recorded in Seattle on August 12, 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: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, or 80°F and above. The official data must be accessed via the NWS website, navigating to the 'Observed Weather' tab and selecting the Daily Climate Report for the correct date. Traders should use the latest available report and remain cautious about potential rounding or conversion discrepancies in preliminary data, as only the final NWS report determines resolution. All secondary instructions consistently direct users to the same authoritative source and emphasize the importance of using the most current data, noting that different locations may update at varying frequencies.
