Latest National Weather Service and NOAA model runs position mid-70s highs as the most likely outcome for Seattle on August 12, with ensemble consensus favoring 76–77°F amid typical late-summer high pressure and moderating Pacific marine influence. Recent warmer-than-average seasonal conditions have kept baseline temperatures elevated, yet no strong heat advection or clear-sky amplification is projected to push values into the low 80s. Traders appear to weigh the narrow forecast spread and historical August variability, where daily highs commonly range 71–82°F, against potential short-term model adjustments before resolution. Upcoming morning updates from local NWS offices will provide the final observational constraints.

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 12 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.
