Forecast models from multiple sources indicate a likely daily minimum temperature in Seattle on August 23 near 57–60°F, driven by a transition to mostly clear skies overnight that enhances radiative cooling while a light northerly wind limits mixing. Seattle’s marine setting near Puget Sound introduces variability through potential advection of cooler air or lingering low-level moisture, which can raise or suppress the low depending on exact cloud cover and boundary-layer winds. With leading market outcomes clustered between sub-54°F and 72°F+ at similar probabilities, traders appear focused on uncertainty in forecast guidance for the precise overnight minimum and local station readings used for resolution. Updated model runs and official NWS observations through the night will likely refine these probabilities ahead of market close.

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 23 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
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 multiple sources indicate a likely daily minimum temperature in Seattle on August 23 near 57–60°F, driven by a transition to mostly clear skies overnight that enhances radiative cooling while a light northerly wind limits mixing.
