**Forecast models from sources like WindBorne Systems and US Harbors indicate a high near 67–68°F for Seattle on September 12, 2026, under mostly cloudy skies with a chance of light rain or showers in the afternoon and evening.** This aligns with the market's leading outcomes (66–67°F at 30% and 68–69°F at 22.5%), reflecting trader consensus around moderate temperatures slightly below the historical average high of ~71°F for the date. Key drivers include persistent cloud cover (often 80–90%) that limits solar heating, light variable winds (typically under 10 mph from the northwest or south), and marine air influence moderating the region. Any timing differences in showers or brief cloud breaks could shift the exact peak by a degree or two, explaining the spread across nearby bins. Recent September conditions have featured similar mild, overcast patterns after warmer early-month days, with no major atmospheric shifts like strong high-pressure systems or offshore flow expected to alter the outlook significantly before resolution.

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.
