Trader consensus clusters around 82–87°F because official forecasts from the National Weather Service and major models indicate sunny conditions with a high near 85°F on August 25, driven by diurnal solar heating under clear skies and light southwest winds. Seattle’s marine layer and Puget Sound typically cap extremes through afternoon sea-breeze cooling, keeping readings well below the 91°F historical record for the date. Minor model spread in peak timing and boundary-layer mixing accounts for the tight 84–85°F and 82–83°F bins holding the largest shares, while any unexpected onshore flow or cloud increase could shift the final maximum downward within the observed uncertainty range.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksea
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Trader consensus clusters around 82–87°F because official forecasts from the National Weather Service and major models indicate sunny conditions with a high near 85°F on August 25, driven by diurnal solar heating under clear skies and light southwest winds.
