Recent official forecasts from the Korea Meteorological Administration and global models indicate a likely minimum of 18–21°C in the Seoul-Incheon area on September 8, driven by clear skies under a strengthening high-pressure system and light northeasterly winds that promote overnight radiative cooling. Current observations show morning lows near 19–20°C, with minimal cloud cover and no significant frontal activity or moisture expected to moderate temperatures. Historical September climatology for the region places typical overnight minima around 18–20°C, supporting the market’s concentration on 19°C as the modal outcome. Updated model runs and KMA briefings over the next 48 hours will provide the key data shifts for 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 8 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 official forecasts from the Korea Meteorological Administration and global models indicate a likely minimum of 18–21°C in the Seoul-Incheon area on September 8, driven by clear skies under a strengthening high-pressure system and light northeasterly winds that promote overnight radiative cooling.
