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 28 Jun '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.**Persistent marine layer cloudiness and limited solar heating are the main drivers keeping Seattle's June 28 high temperature forecast centered in the mid-to-upper 60s.** National Weather Service guidance currently projects a mostly cloudy day with a high near 68°F, while other models and services range from 64–68°F amid south winds of 5–8 mph. Seattle’s coastal location and Puget Sound influence typically suppress daytime maxima in late June relative to inland areas, and recent forecasts show no strong high-pressure ridging to clear skies or boost temperatures. This narrow expected range explains the tight market clustering around 64–69°F outcomes, with traders weighing minor differences in model timing of any sun breaks or cloud persistence that could shift the daily maximum by a degree or two. Updated NWS and model runs over the next 24 hours will provide the clearest signals ahead of resolution.
