Recent NOAA and ensemble model guidance for Seattle on September 21 points to a mild high in the upper 60s to low 70s under partly cloudy skies with light northerly flow, driving the market's tight clustering around 66–71 °F bins. Persistent high pressure and minimal marine-layer intrusion limit afternoon warming compared with recent warmer days, while patchy morning fog and variable cloud cover create the main uncertainty between the 66–67 °F and 70–71 °F outcomes. Historical September climatology shows similar late-summer patterns can shift several degrees with small changes in onshore flow or insolation. Traders appear to price the narrow forecast spread and typical model divergence near the event, with resolution hinging on the official Sea-Tac maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 21 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Recent NOAA and ensemble model guidance for Seattle on September 21 points to a mild high in the upper 60s to low 70s under partly cloudy skies with light northerly flow, driving the market's tight clustering around 66–71 °F bins.
