Clear skies and light northerly winds under high pressure are driving Seattle's afternoon temperatures toward a daily high in the low to mid-70s on September 16, 2026. Official National Weather Service guidance and multiple model runs converge on a peak near 72–73°F, modestly above the 1991–2020 September average high of 70.6°F, with current readings at Sea-Tac and downtown stations already reaching 72°F by mid-afternoon. The absence of cloud cover or marine layer intrusion allows efficient solar heating, while minimal wind shear limits cooling. Trader consensus heavily favors the 74–75°F bin (71.5% implied probability) over 72–73°F (25%), reflecting slight upward bias in recent observations or ensemble spread that could push the official maximum one degree higher before sunset. Updated NWS briefings and final hourly readings will resolve the market.

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 16 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.Clear skies and light northerly winds under high pressure are driving Seattle's afternoon temperatures toward a daily high in the low to mid-70s on September 16, 2026.
