Recent forecasts from the Korea Meteorological Administration and ensemble models indicate an overnight low in Incheon around 18–19°C on September 17, with trader consensus clustered on these outcomes due to stable high-pressure conditions and easterly flow. Partly cloudy skies and light to moderate easterly winds (5–8 m/s) are expected to limit radiational cooling compared to clearer nights earlier in the week, while dew points near 14–16°C support minimum temperatures in the upper teens Celsius. Model spread arises from subtle differences in cloud cover timing and boundary-layer mixing, with some runs favoring 17°C under clearer conditions and others 19–20°C if marine influence strengthens. Historical September climatology for the region shows typical overnight lows near 18°C, aligning with current data and keeping probabilities tightly grouped ahead of updated model runs.

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 the Korea Meteorological Administration and ensemble models indicate an overnight low in Incheon around 18–19°C on September 17, with trader consensus clustered on these outcomes due to stable high-pressure conditions and easterly flow.
