Forecast models from NOAA and regional sources indicate Seattle’s September 1 high will likely fall in the low-to-mid 70s°F, aligning with the market’s near-even split between the 72–73°F and 74–75°F bins. Persistent marine influence, variable cloud cover, and light southerly winds are limiting daytime heating below late-August peaks, while the historical average high of 74°F provides a benchmark. Minor model disagreements on exact cloud timing and marine-layer depth create the tight probability distribution, with any clearing trend potentially pushing readings toward the upper bin and increased onshore flow favoring the lower. Updated NWS guidance and afternoon observations on August 31 will refine these short-range uncertainties 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 1 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.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Forecast models from NOAA and regional sources indicate Seattle’s September 1 high will likely fall in the low-to-mid 70s°F, aligning with the market’s near-even split between the 72–73°F and 74–75°F bins.
