Latest National Weather Service guidance and regional model runs point to a Seattle high near 80–82°F on August 20, driven by gradual clearing of morning marine stratus followed by mostly sunny skies and light northwesterly flow. This aligns with traders clustering probability on the 80–83°F bands amid typical mid-August Pacific moderation, where the Puget Sound’s cool marine layer and onshore breeze limit extremes despite above-normal seasonal baselines around 77–79°F. Key uncertainties include the precise timing of cloud dissipation and boundary-layer mixing, which can shift peak readings by 2–3°F; stronger onshore winds or lingering stratus would favor the lower 80s, while clearer conditions and calm winds support the upper end. Updated NWS point forecasts tomorrow morning will refine these thresholds ahead of resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 20 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Seattle-Tacoma International Airport Station, available here: https://www.wunderground.com/history/daily/us/wa/seatac/KSEA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
