Recent forecasts from NOAA-affiliated and meteorological sources for Seattle on August 28, 2026, converge on a daytime high near 70°F, with morning cloud cover and a slight chance of showers giving way to partly sunny skies and light winds. This supports the market’s heavy weighting toward the 70–73°F range, as marine layer influence and modest onshore flow limit peak solar heating compared to clearer summer days. Model runs show minimal disagreement, with temperatures unlikely to exceed mid-70s absent unexpected clearing or offshore flow. The 72–73°F bin leads because several guidance packages peak in that narrow window, while lower outcomes reflect the baseline risk of persistent stratus. Final NWS updates and morning observations on the 28th remain the key variables that could nudge probabilities before resolution.

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 28 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
