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 1 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. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.
Seattle's highest temperature on September 1 is expected near 70–75°F under partly sunny skies, with National Weather Service guidance indicating a high around 75°F amid light southwest winds and limited marine influence. Multiple forecast models cluster in the low-to-mid 70s, reflecting modest diurnal heating under variable cloud cover rather than strong radiational warming or marine-layer suppression. Trader sentiment splits evenly between the 70–71°F and 72–73°F bins because small differences in afternoon insolation, wind timing, or boundary-layer mixing can shift the daily maximum by 1–2°F within typical model spread. Historical early-September averages near 74°F provide context, but the immediate forecast favors values below that threshold as a weak frontal approach begins to increase cloudiness by evening.
