Recent forecasts from multiple models indicate the overnight minimum in Incheon on September 17 will likely fall between 17–19 °C under partly to mostly cloudy skies and light easterly flow. High pressure and seasonal radiative cooling favor these values, with historical September lows averaging near 18 °C. No significant frontal systems or moisture advection are expected to alter the trajectory before resolution. Trader consensus, reflected in the 43 % implied probability for 18 °C and 31 % for 19 °C, aligns with the current model envelope while acknowledging minor uncertainty from cloud-cover variations and exact wind speeds that could shift the reading by 1 °C. Updated guidance from the Korea Meteorological Administration or equivalent agencies later on September 16 or early September 17 will provide the final inputs for market resolution.

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 17 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 multiple models indicate the overnight minimum in Incheon on September 17 will likely fall between 17–19 °C under partly to mostly cloudy skies and light easterly flow.
