Recent National Weather Service forecasts and ensemble model guidance indicate a high near 76–77°F for Seattle on September 9, driven by clearing skies, light northerly flow, and seasonal solar insolation under a building high-pressure ridge following cooler, partly cloudy conditions earlier in the week. This positions the 76–77°F and 78–79°F bins as market leaders, consistent with the 72.2°F historical average high for the date and recent observed maxima in the low to mid-70s. Traders appear to weigh the low probability of significant deviation given stable synoptic patterns and minimal precipitation risk, though minor forecast adjustments from updated model runs could shift implied probabilities ahead of resolution.

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 9 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 forecasts and ensemble model guidance indicate a high near 76–77°F for Seattle on September 9, driven by clearing skies, light northerly flow, and seasonal solar insolation under a building high-pressure ridge following cooler, partly cloudy conditions earlier in the week.
