Recent short-range forecasts from the National Weather Service and ensemble models point to a high near 72–73°F for Seattle on September 1, driven by moderating onshore flow from the Pacific and increasing afternoon cloud cover that limits daytime heating. This places the outcome just below the early-September climatological average of roughly 74°F while remaining well above cooler marine-layer scenarios that have produced 68–70°F readings in similar setups. Trader consensus clusters tightly around the 70–75°F range because small differences in the strength of the thermal trough or marine push can shift the peak by a few degrees, with new model runs and observational updates expected to refine probabilities through the final 48 hours.

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.
