**Clear skies and light easterly winds across the Seoul-Incheon region on September 21, 2026, have supported overnight radiative cooling, with official and model guidance converging on a minimum temperature of 19°C.** Forecasts from the Met Office and multiple international sources list the nighttime low near 18–21°C under mostly clear conditions, consistent with typical late-September climatology for the area (average lows around 18°C). Real-time observations, including airport reports near 18°C in the afternoon UTC window, reinforce trader confidence that the daily minimum will settle at 19°C. The market-implied 100% probability on this outcome reflects the strong alignment of current data and limited variability in steering patterns or moisture. Only an unexpected increase in cloud cover, stronger winds, or a late measurement revision from the Korea Meteorological Administration could alter the recorded low.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 21 Sep '26.
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.**Clear skies and light easterly winds across the Seoul-Incheon region on September 21, 2026, have supported overnight radiative cooling, with official and model guidance converging on a minimum temperature of 19°C.**
