**Clear skies, light northeasterly winds, and stable high pressure are positioning the overnight low in Incheon (Seoul area) near 19–20 °C on September 7, 2026, driving the market’s heavy weighting toward 20 °C (51.5 %) and 19 °C (25.0 %).** Official and ensemble forecasts from sources including the Korea Meteorological Administration, WeatherBug, and PredictWind show the minimum temperature falling to roughly 17–20 °C under mostly clear conditions, with dew points in the mid-teens Celsius limiting further radiative cooling. This range aligns with early-September climatology for the region once the summer monsoon retreats and northeasterly flow brings drier, slightly cooler air. Recent model runs have converged on these values with minimal spread, and no significant frontal passages or increased cloud cover are expected through the night of the 6th–7th. The 18 °C outcome (12.5 %) remains plausible if winds stay calm or if localized cooling is stronger than modeled, while probabilities drop sharply below 18 °C or above 21 °C because current guidance shows little support for those extremes. Traders are therefore pricing in the narrow, well-forecasted window around the seasonal average 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 7 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, light northeasterly winds, and stable high pressure are positioning the overnight low in Incheon (Seoul area) near 19–20 °C on September 7, 2026, driving the market’s heavy weighting toward 20 °C (51.5 %) and 19 °C (25.0 %).**
