Current forecast models from NOAA and NWS consensus place Seattle's August 18 high temperature in the mid to upper 70s, driven by typical marine-layer moderation from Puget Sound onshore flow that caps daytime warming under a building but not dominant ridge. Ensemble runs show limited spread around 76–79°F, reflecting uncertainty in exact cloud cover, wind strength, and boundary-layer mixing rather than major synoptic shifts. This aligns with August climatology near 76–77°F and explains tight market clustering on 74–79°F bins, as small deviations in those variables can shift the peak by a degree or two without crossing extreme thresholds. Updated model guidance expected overnight will further refine the range.

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 18 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.
