Current National Weather Service forecasts place Seattle's peak temperature on August 18 in the mid-to-upper 70s, reflecting a moderate onshore flow and lingering marine layer that caps daytime heating under a weak Pacific high. The closely matched 76-77°F and 78-79°F outcomes stem from minor model differences in boundary-layer mixing, cloud timing, and dew-point depression, which control how much solar insolation reaches the surface before the sea breeze strengthens. Historical late-August climatology shows typical highs near 75–78°F, so traders weigh any updated runs from the NAM or ECMWF that could shift the maximum by 1–2°F. Resolution hinges on official Seattle-Tacoma Airport readings at 5 p.m. local time, where precise humidity and wind observations determine the final peak.

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.
