**Recent official forecasts for Incheon/Seoul on September 24, 2026, center on a daily high of 24–26°C under partly cloudy to overcast skies with light northwest winds.** Multiple sources, including WeatherBug, Meteum, Met Office, and PredictWind, indicate highs near 76–79°F (24–26°C), consistent with late-September climatology as seasonal cooling sets in after summer. These conditions—moderate humidity, minimal precipitation risk, and stable steering patterns—support the market’s tight clustering around 24°C (26.5%), 25°C (40.0%), and 26°C (25.0%), which together exceed 90% implied probability. Model consensus shows little spread, with no strong warm advection or clear-sky radiative heating expected to push readings to 27°C or above, nor cold-air intrusions likely to drop them to 23°C or below. Traders appear to be weighting the latest numerical guidance and historical analogs for the date, which favor this narrow range over outliers. Updated model runs or morning observations on the 24th could refine the exact peak, but current data leave limited room for significant deviation.

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 24 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 official forecasts for Incheon/Seoul on September 24, 2026, center on a daily high of 24–26°C under partly cloudy to overcast skies with light northwest winds.** Multiple sources, including WeatherBug, Meteum, Met Office, and PredictWind, indicate highs near 76–79°F (24–26°C), consistent with late-September climatology as seasonal cooling sets in after summer.
