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 16 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent National Weather Service guidance and ensemble forecasts for Seattle on August 16 point to a high near 74–77°F, reflecting the moderating influence of persistent onshore marine air and light zonal flow aloft that limits daytime heating despite a broader warmer-than-average Pacific Northwest pattern. This setup aligns closely with mid-August climatology, where average highs reach 76–79°F at Seattle-Tacoma International Airport with low day-to-day variability. Subtle differences among closely matched market outcomes hinge on minor forecast variations in cloud cover, dew points, and afternoon wind speeds that can shift maximum temperatures by 1–3°F. Updated model runs and official observations through the evening will refine resolution criteria based on the daily maximum reading.
