Recent National Weather Service and private model guidance points to overnight radiative cooling under mostly clear skies, with Seattle's daily minimum on August 25 expected near 55–59°F amid typical late-summer marine influence and light winds. This range aligns with climatological August lows of 56–57°F and supports the tight clustering of trader-implied probabilities around 56–61°F. Key variables differentiating the leading bins include subtle differences in cloud cover timing, dew-point depression, and urban heat-island effects that can shift the observed minimum by 1–3°F. Updated model runs and evening observations from Sea-Tac Airport will refine the final reading before market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
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.
