**Official observations from the National Weather Service at Seattle-Tacoma International Airport recorded a maximum temperature of 63°F on September 19, 2026, at 4:59 PM local time.** This placed the daily high 8°F below the 1991–2020 normal of 71°F and well short of historical September 19 records near 86°F. The minimum reached 52°F under mostly cloudy to overcast skies with calm winds and areas of mist, conditions that limited daytime heating and kept readings suppressed relative to seasonal averages. Trader sentiment, reflected in the 99.9% implied probability for 63°F or below, aligns directly with this verified NWS climatological report, which serves as the authoritative source for market resolution. The outcome sits comfortably within the typical late-September range for the Pacific Northwest, where marine influence and cloud cover frequently cap highs. Realistic scenarios that could have challenged the positioning include a late-day clearing trend allowing additional solar heating, a shift in steering patterns bringing warmer air from the east, or model runs earlier in the week projecting temperatures several degrees higher. However, the actual atmospheric conditions produced a clear, data-backed result consistent with the strong market consensus.

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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
