Recent National Weather Service forecasts and observational data from Seattle-Tacoma International Airport (KSEA) have driven the market's 100% consensus on an 86-87°F high for August 6, reflecting persistent high-pressure ridging that suppressed marine layer cooling and allowed daytime temperatures to peak in the upper 80s amid typical late-summer conditions. Official model guidance consistently projected this range without significant deviation from climatological norms, where August averages hover near 76°F. Realistic challenges could include an unforecasted onshore flow shift or station-specific measurement variance that alters the final reported maximum.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 6 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Seattle-Tacoma International Airport Station, available here: https://www.wunderground.com/history/daily/us/wa/seatac/KSEA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
