Latest National Weather Service and ensemble model guidance points to a Sunday high temperature in Seattle near 69–72 °F, supporting the market’s leading 70–71 °F bin. A lingering upper-level trough and associated marine influence are expected to produce morning cloud cover that limits daytime heating, while light southerly flow and only modest onshore push keep readings below late-August climatological averages of 74–76 °F. Saturday’s coastal disturbance brings showers and slightly cooler air that moderates further Sunday warming, yet partial afternoon clearing allows the temperature to reach the upper 60s to low 70s. Traders appear to weight the tight clustering of deterministic and statistical guidance, with resolution hinging on the final observed maximum at official stations before any late-day marine-layer reinforcement.

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 30 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.
