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 4 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.
Current National Weather Service and ensemble forecasts for Seattle on September 4, 2026, point to a daytime high of 68–71°F, aligning with the market’s leading 70–71°F outcome at 54.5% implied probability. Persistent onshore flow and a marine layer from the Pacific are capping daytime warming, with partly to mostly cloudy skies and a chance of morning showers limiting solar heating. This setup follows a below-normal 68–69°F high on September 3 and sits several degrees under the 1991–2020 climatological average of 73°F. Model consensus shows modest afternoon clearing that could allow readings to reach the low 70s in sheltered areas, while stronger marine push keeps readings closer to 68°F. Resolution hinges on official Seattle-Tacoma Airport observations, with traders weighting the latest NWS guidance most heavily.
