**Forecast consensus from National Weather Service and private models points to a Seattle overnight low of 52–54°F on September 18, 2026, under partly cloudy to mostly clear skies with light southerly winds.** Clear conditions overnight promote radiational cooling as the ground loses heat efficiently, while the marine influence of Puget Sound and typical September climatology (historical average low near 52–53°F) limit further drops. Recent high-pressure dominance has kept skies clear and winds light across the region, supporting steady cooling without cold-air advection or cloud cover that would moderate temperatures. Model runs show minimal spread, with most guidance clustering in the low-to-mid 50s; any deviation would require an unexpected increase in cloud cover or wind shift before dawn. Traders have concentrated probability on the 52–55°F bins, reflecting this narrow, data-driven range ahead of the overnight period.

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 18 Sep '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.
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.**Forecast consensus from National Weather Service and private models points to a Seattle overnight low of 52–54°F on September 18, 2026, under partly cloudy to mostly clear skies with light southerly winds.**
