Recent weather model runs from global forecasting centers show Seoul's maximum temperature on September 9 likely settling near 25–26°C, producing the market's near-even split between those outcomes. A weak high-pressure ridge is promoting mostly clear skies and light southerly flow, yet increasing mid-level moisture and scattered afternoon cloud build-up introduce modest cooling potential that could cap the high at 25°C. Seasonal climatology places early-September averages at 26°C, but daily variability from urban heat retention and localized sea-breeze effects keeps the range narrow. Updated model guidance later today will clarify whether stronger insolation or increased cloud cover shifts the balance.

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 9 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 weather model runs from global forecasting centers show Seoul's maximum temperature on September 9 likely settling near 25–26°C, producing the market's near-even split between those outcomes.
