Latest National Weather Service and model guidance point to a Seattle high temperature of 66–68°F on September 21, driven by a strengthening marine layer that increases afternoon cloud cover and caps solar heating. Light northwesterly winds and dew points near 52–55°F limit surface warming, while the seasonal decline in insolation keeps values below late-summer peaks. Ensemble spreads remain narrow because steering patterns and sea-surface temperatures show little day-to-day variability. Traders assign the highest implied probabilities to the 66–67°F and 68–69°F bins precisely because official forecasts cluster there, with resolution hinging on whether midday clearing allows a brief push into the upper 60s or persistent stratus holds readings lower.

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 21 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 National Weather Service and model guidance point to a Seattle high temperature of 66–68°F on September 21, driven by a strengthening marine layer that increases afternoon cloud cover and caps solar heating.
