Latest National Weather Service forecasts and model guidance point to a minimum temperature in the mid-to-upper 50s for Seattle on August 25, driven by strengthening onshore flow and marine air advection ahead of an approaching upper-level low. This pattern favors overnight radiative cooling under partly to mostly cloudy skies, limiting daytime heating and keeping surface temperatures near seasonal norms of 56°F. Recent upper-air analyses show the trough enhancing westerly winds that moderate extremes, with ensemble spreads centering outcomes between 56–59°F. Traders weigh these dynamics against potential clearer breaks that could dip readings slightly lower, while noting typical August variability rarely pushes below 53°F without stronger synoptic cooling.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.
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.Latest National Weather Service forecasts and model guidance point to a minimum temperature in the mid-to-upper 50s for Seattle on August 25, driven by strengthening onshore flow and marine air advection ahead of an approaching upper-level low.
