Recent National Weather Service and model guidance for Seattle on September 20, 2026, centers on a daytime high near 69°F under partly sunny skies, light northerly winds, and stable high pressure, aligning with the market's leading 68-69°F bin. Subtle differences among nearby outcomes stem from forecast variability in peak solar insolation, marine layer influence, and exact afternoon cloud cover, which can shift maxima by 1–2°F. Historical averages for the date hover around 69°F, providing context for the tight clustering of probabilities. Final NWS observations tomorrow will resolve the market, with any last-minute model adjustments likely to refine trader positioning ahead of verification.

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 20 Sep '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.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 for Seattle on September 20, 2026, centers on a daytime high near 69°F under partly sunny skies, light northerly winds, and stable high pressure, aligning with the market's leading 68-69°F bin.
