**Official meteorological observations for Seoul-Incheon on September 19, 2026, show a daily minimum temperature of 20°C, aligning with the market's near-certain 100% implied probability on that exact outcome.** Multiple forecast models and real-time station reports from the region, including Incheon International Airport and central Seoul sites, recorded overnight lows stabilizing near 19–21°C under clear to partly cloudy skies with light northeasterly winds and dew points around 13–16°C. This matches typical mid-September climatology for the area, where average minima hover near 17–19°C but can run warmer during stable high-pressure setups. The overwhelming trader consensus reflects these verified measurements and the absence of any late-day cooling that could drop readings below 19°C. Only an unexpected measurement revision from the primary reporting station or a highly localized microclimate anomaly would realistically alter 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=rksi
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 Metric Units" button until the relevant table displays °C.
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 Celsius (eg, 9°C). 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.
