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.
Current forecast models from sources including GFS and regional agencies indicate overnight lows for Seoul and Incheon on September 8 will likely settle between 17–20 °C, driving the tight market split between 19 °C and 20 °C. Clear to partly cloudy skies and light variable winds under high pressure favor moderate radiative cooling after sunset, with dew points near 16–18 °C limiting further drops; urban heat retention in Seoul versus the more exposed Incheon airport site creates minor local variance. Ensemble spreads remain narrow given stable synoptic conditions and no incoming fronts, though small revisions in cloud cover or boundary-layer mixing could shift the realized minimum by 1 °C. Updated model runs and official Korea Meteorological Administration guidance expected overnight will provide the next key inputs for traders.
