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 20 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 and NOAA forecasts for Seattle on August 20 project daytime highs in the low-to-mid 80s°F, driven by typical late-summer high pressure with reduced marine-layer cooling and light onshore flow that limits extreme warming. Ensemble model consensus and climatological baselines around 77°F normal support the market's heavy weighting toward the 82-83°F and 84-85°F bins, reflecting observed recent trends of above-average temperatures amid a broader warmer-than-normal summer outlook. Key variables include potential afternoon sea-breeze moderation or clearer skies that could nudge readings slightly higher, with final official measurements from Sea-Tac Airport determining resolution.
