Recent forecasts from agencies including the Korea Meteorological Administration and international models converge on a daytime high near 26°C for Seoul-Incheon on September 23 under persistent high pressure, light southeasterly winds, and partly cloudy skies that limit both extreme heating and cooling. This places the 26°C outcome at the center of trader-implied probabilities (53.5%), with 25°C and 27°C as secondary possibilities reflecting typical forecast spread and local microclimate differences between the two stations. Late-September climatology shows average highs around 23–25°C, so current conditions represent a modest warm anomaly sustained by the lack of incoming frontal systems or significant moisture. New model runs and KMA updates expected overnight will likely refine the precise peak before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 23 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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 agencies including the Korea Meteorological Administration and international models converge on a daytime high near 26°C for Seoul-Incheon on September 23 under persistent high pressure, light southeasterly winds, and partly cloudy skies that limit both extreme heating and cooling.
