Recent forecasts from the Korea Meteorological Administration and international models indicate overnight lows near 19–21°C for Incheon/Seoul on September 6 under clear to partly cloudy skies and persistent northeasterly flow, which limits daytime heating while allowing radiational cooling at night. Trader positioning, with 14°C or below at 50% implied probability alongside notable shares near 19–20°C, reflects model spread in minimum temperature guidance and uncertainty over exact boundary-layer moisture and wind speeds that could enhance or suppress nocturnal cooling. Historical September baselines for the region average daily minima around 18–20°C, making current consensus forecasts the main anchor, though short-term adjustments from updated KMA or ECMWF runs could shift resolution odds before the daily minimum is recorded.

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.
