Trader consensus centers on a minimum temperature of 52–57°F for Seattle on September 8, with the 54–55°F bin holding the highest implied probability at 40%. Official National Weather Service and model guidance indicate clear to mostly clear skies under building high pressure and northerly flow, supporting radiational cooling after daytime highs in the upper 60s to mid-70s. Recent observations show overnight lows of 52–53°F on September 5–6, consistent with early-September climatology (average low 54.4°F). Limited cloud cover and light winds overnight are expected to prevent significant warming, while the absence of marine intrusions or frontal systems keeps temperatures from dropping below the low 50s. Updated model runs and the next NWS forecast discussion will provide the primary near-term catalyst for any shifts in these market-implied odds.

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 8 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.Trader consensus centers on a minimum temperature of 52–57°F for Seattle on September 8, with the 54–55°F bin holding the highest implied probability at 40%.
