Recent National Weather Service and model guidance indicate a daily high near 73–75°F for Seattle on August 23, aligning with the market’s leading bins. Persistent onshore flow and a moderating marine layer typical of late-summer Pacific Northwest conditions are capping daytime heating, while above-average seasonal warmth from the broader 2026 summer pattern provides modest support for the upper end of that range. Ensemble spread remains narrow, reflecting limited uncertainty in steering patterns and boundary-layer moisture ahead of the event. Traders are weighting the 74–75°F outcome most heavily because verification will use the official Sea-Tac maximum, and historical August variability rarely produces deviations exceeding a few degrees once the 48-hour forecast window is reached.

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 23 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
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.Recent National Weather Service and model guidance indicate a daily high near 73–75°F for Seattle on August 23, aligning with the market’s leading bins.
