Recent forecasts from the Korea Meteorological Administration and major models indicate a minimum temperature near 18–19°C in the Incheon/Seoul area on September 21 under clear skies and light northerly flow. Stable high pressure supports efficient nighttime radiative cooling with low humidity and minimal cloud cover, while weak winds limit mixing that could raise overnight lows. Consensus across updated runs shows little day-to-day shift, keeping the market closely split between 18°C, 19°C, and 20°C outcomes. Traders weigh subtle differences in local station siting, exact timing of the daily minimum, and any late adjustments to boundary-layer conditions before the event resolves.

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.
