Latest forecast guidance from NOAA and private models shows Seattle under high pressure with clearing skies and northerly flow on September 8, supporting a high near 72°F as the most likely outcome. This aligns closely with the 1991–2020 climatological average of 72.4°F and recent model runs that have held steady without significant warm or cool biases. Trader positioning reflects this narrow range, with the 72–73°F and 74–75°F bins capturing nearly 80% of implied probability amid typical ensemble spread of a few degrees. Key variables to watch include afternoon mixing depth and any late-day marine layer intrusion, which could cap or boost the peak by 1–2°F before official observations finalize the market.

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 8 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.Latest forecast guidance from NOAA and private models shows Seattle under high pressure with clearing skies and northerly flow on September 8, supporting a high near 72°F as the most likely outcome.
