Official National Weather Service observations at Seattle-Tacoma International Airport recorded a minimum temperature of 58°F on August 26, 2026, achieved near dawn under mostly cloudy to partly clear skies with light southerly winds around 6 mph. This value sits just 1°F above the 1991–2020 climatological normal low of 57°F for the date, reflecting typical late-summer radiative cooling absent any strong warm advection or persistent cloud cover that would suppress overnight temperature drops. The market’s 100% consensus on the 58–59°F bin reflects the absence of measurement revisions or alternative station discrepancies. Only an undetected sensor error or a highly localized microclimate anomaly differing from the official airport site could realistically alter resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 26 Aug '26.
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.
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.
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.Official National Weather Service observations at Seattle-Tacoma International Airport recorded a minimum temperature of 58°F on August 26, 2026, achieved near dawn under mostly cloudy to partly clear skies with light southerly winds around 6 mph.
