Recent influx of cooler, drier air from a northern high-pressure system has moderated Seoul and Incheon temperatures after early-September peaks near 31°C. Latest KMA and international model runs project a Friday high of 25–26°C under mostly clear to partly cloudy skies, with light northwest winds and minimal precipitation risk supporting modest daytime heating. The near-even split between 25°C and 26°C market-implied odds reflects small forecast variations in afternoon cloud cover and exact wind timing, which can alter peak solar insolation by 1°C. Historical September averages near 24°C provide context, while the next KMA update and ECMWF runs before resolution will likely tighten the range.

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 11 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 influx of cooler, drier air from a northern high-pressure system has moderated Seoul and Incheon temperatures after early-September peaks near 31°C.
