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 7 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 National Weather Service and model guidance points to a high near 68–69°F in Seattle on September 7, driven by persistent onshore flow and marine-layer stratus that limit daytime heating below the 72.6°F climatological average. Light southwesterly winds and 30–60% cloud cover, with a chance of drizzle, further suppress temperatures after recent days that reached 72–74°F. Trader consensus around the 68–71°F bins reflects this consensus forecast and the narrow historical range for early-September highs, while lower-probability outcomes would require unexpected clearing or stronger offshore flow not currently indicated in official guidance. Updated NWS briefings and Sea-Tac observations tomorrow will determine final resolution.
