Recent official forecasts from the National Weather Service and multiple meteorological sources indicate Seattle will see morning cloud cover gradually clearing by afternoon on August 30, 2026, allowing solar heating to drive daytime highs into the upper 60s to low 70s. Light southerly winds and moderate humidity under a stable marine layer limit further warming, consistent with late-summer climatology where Puget Sound’s oceanic influence caps peaks near 70°F. Live model consensus and hourly observations through midday support a maximum temperature most likely in the 68–71°F range, with minimal precipitation risk reinforcing these conditions. Market-implied odds align closely with this evidence-based outlook ahead of final daily maximum readings.

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.
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 official forecasts from the National Weather Service and multiple meteorological sources indicate Seattle will see morning cloud cover gradually clearing by afternoon on August 30, 2026, allowing solar heating to drive daytime highs into the upper 60s to low 70s.
