Official National Weather Service observations at Seattle-Tacoma International Airport recorded a daily maximum of 68–69°F on September 4, 2026, under overcast skies with light winds and trace precipitation. This aligns with climatological norms near 73°F for early September yet reflects cooler-than-average conditions driven by marine air influence and cloud cover suppressing daytime heating. Market-implied odds at 100% for this bin reflect trader consensus grounded in real-time station data and model verification, with minimal uncertainty once preliminary climatological reports are issued. Rare post-analysis revisions to the official high or use of an alternate Seattle station could theoretically alter resolution, though historical precedent shows such adjustments are infrequent for this metric.

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 4 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.Official National Weather Service observations at Seattle-Tacoma International Airport recorded a daily maximum of 68–69°F on September 4, 2026, under overcast skies with light winds and trace precipitation.
