Current National Weather Service and model guidance points to a low in the lower to mid-50s for Seattle on September 20 under mostly clear skies, light northerly winds, and dry conditions that favor nocturnal radiative cooling. With high pressure dominating and no significant frontal systems approaching, overnight temperatures are expected to bottom out near 51–53°F at official stations, though urban heat islands or slight variations in cloud timing could nudge readings into adjacent bins. Historical September climatology shows similar calm nights producing lows clustered around 50–54°F, and the closely matched 50–51°F and 52–53°F market shares reflect traders pricing in this narrow forecast spread plus residual model uncertainty ahead of final verification.

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 20 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.Current National Weather Service and model guidance points to a low in the lower to mid-50s for Seattle on September 20 under mostly clear skies, light northerly winds, and dry conditions that favor nocturnal radiative cooling.
