Recent National Weather Service guidance and ensemble model consensus center the Seattle high on August 18 in the upper 70s, aligning with mid-August climatology of 77–79°F amid the region’s 14th consecutive warmer-than-average summer. Model divergence in the strength and timing of onshore flow and marine layer influence creates the tight split between the 76–77°F and 78–79°F bins, which together capture over 60% of market-implied probability. Warmer-than-normal Pacific sea-surface temperatures have supported elevated baselines, while any strengthening of the thermal trough or delayed marine push could shift the peak into the low 80s. Traders are monitoring the next NWS forecast updates and high-resolution model runs for resolution signals ahead of the daily maximum observation.

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.
