This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 29 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksea This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. 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.
Forecasts for Seattle on August 29 show a cooler-than-normal day driven by widespread morning rain, lingering cloud cover, and a chance of afternoon showers or isolated thunderstorms, which limit solar heating and keep maximum temperatures in the mid-to-upper 60s. Official guidance from the National Weather Service and other models points to a high near 66–71°F under light southerly winds and marine-influenced air from Puget Sound, well below the late-August climatological average of roughly 75°F. This supports the market’s strong emphasis on the 68–69°F bin, with secondary probability on 66–67°F, as traders weigh the cooling effects of precipitation and reduced insolation against any potential afternoon clearing. Updated model runs and real-time observations will refine these implied probabilities as the day progresses.
