Recent forecasts from the Korea Meteorological Administration and international models indicate a minimum temperature of 18–19°C in Incheon on September 20 under clear skies and light northerly winds, driving the market’s heavy weighting toward those outcomes. Stable high-pressure conditions and consistent model consensus have kept probabilities elevated for 19°C (69.5%) and 18°C (25.5%), reflecting typical late-September climatology without cold-air advection or significant cloud cover that could depress readings further. Traders are monitoring the final overnight model runs and official KMA updates, as minor shifts in wind or dew-point forecasts could adjust the exact low within the narrow 17–20°C range.

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 20 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.Recent forecasts from the Korea Meteorological Administration and international models indicate a minimum temperature of 18–19°C in Incheon on September 20 under clear skies and light northerly winds, driving the market’s heavy weighting toward those outcomes.
