Recent numerical weather prediction models and Korea Meteorological Administration guidance point to clear skies and light winds under a persistent high-pressure ridge, favoring radiative cooling with an overnight low near 19°C for Incheon on September 22. This places the most likely outcome between the market’s 14°C-or-below and 24°C-or-higher brackets, whose near-even implied probabilities reflect residual uncertainty in exact minimum timing and local urban heat-island effects. Diurnal temperature ranges of 9–11°C are typical for late-September Seoul under such conditions, while any increase in low-level moisture or wind would limit cooling. Updated KMA short-range forecasts and real-time observations on the 22nd will provide the final resolution data.

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.
