**Current forecast models indicate a high of 66–68°F for Seattle on September 14, driven by lingering marine influence and cloud cover following a frontal passage.** Light southerly winds and high humidity are expected to limit daytime heating, with conditions ranging from overcast to partly sunny and only a low chance of drizzle. This keeps temperatures near or slightly below the late-summer climatological average of 71°F. The near-even market split between the 66–67°F and 68–69°F bins captures small differences across model runs regarding the timing and extent of any afternoon clearing. Official guidance from monitoring agencies and ensemble outputs will refine the exact peak as the day progresses.

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 14 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 forecast models indicate a high of 66–68°F for Seattle on September 14, driven by lingering marine influence and cloud cover following a frontal passage.** Light southerly winds and high humidity are expected to limit daytime heating, with conditions ranging from overcast to partly sunny and only a low chance of drizzle.
