Recent forecasts from the Korea Meteorological Administration and international models indicate mostly clear skies and light northerly winds over Seoul and Incheon on September 21, 2026, supporting an overnight low near 18–19 °C. High pressure dominates with minimal cloud cover and dew points in the mid-teens, allowing efficient radiational cooling after daytime highs of 28–30 °C. Model consensus shows little disagreement on steering patterns or moisture, keeping probabilities concentrated on 18–20 °C outcomes. Updated runs through September 20 confirm stable conditions without incoming fronts, aligning trader sentiment with the 19 °C bin as the modal 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.
