Forecast models from agencies including the Korea Meteorological Administration indicate a daily maximum near 25–27°C for Incheon on September 24, 2026, under mostly cloudy to partly cloudy skies with light northwesterly winds and moderate humidity. This range aligns with the seasonal transition in late September, when regional highs typically moderate from summer peaks as solar angles decrease and onshore flow persists. Recent observations show overnight lows around 18–20°C and limited daytime heating due to cloud cover, keeping the most probable outcome at 26°C. Trader consensus reflected in the 55% implied probability for 26°C incorporates these stable synoptic conditions, while the 22.5% on 27°C accounts for any model spread or localized warming if skies clear more than expected. Official station data will resolve the market once the daily maximum is recorded.

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.
