**Recent forecasts from the National Weather Service and other models indicate a high near 66–68°F for Seattle on September 11, 2026, under mostly cloudy to overcast skies with light southerly flow and a slight chance of drizzle.** This positions the 66–67°F and 68–69°F bins as the clear market leaders at 40.5% and 29.5% implied probability, respectively, while warmer outcomes above 70°F receive only single-digit support. The cooling trend stems from a shift to onshore marine air after several days of clearer, warmer conditions earlier in the week (highs in the low-to-mid 70s). Increased cloud cover limits solar heating, and the light southerly winds advect cooler Pacific air, keeping afternoon maxima below the September climatological average of roughly 72°F. Model consensus shows limited spread, with most guidance clustered in the mid-to-upper 60s and minimal risk of significant warming or cooling outliers. Traders appear to be weighting the latest official guidance and historical analogs for similar late-summer marine intrusions, resulting in tight clustering around the forecast range. Resolution will depend on the official high reported from Seattle-Tacoma International Airport or the designated station, with final NWS observations expected to confirm the outcome.

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.
