Recent forecasts from the Korea Meteorological Administration and global models indicate persistent cloud cover and widespread rain across the Seoul-Incheon region on August 31, driven by a slow-moving frontal boundary. This setup reduces incoming solar radiation and enhances evaporative cooling, capping daytime maxima near 25–26 °C. The narrow spread between those two leading outcomes reflects uncertainty in rainfall timing and any brief afternoon breaks in the cloud deck that could allow slightly greater surface heating. Northeast winds and elevated dew points further limit sensible heat buildup, keeping probabilities tightly clustered while rendering 27 °C or higher far less likely under current atmospheric conditions.

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 31 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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 the Korea Meteorological Administration and global models indicate persistent cloud cover and widespread rain across the Seoul-Incheon region on August 31, driven by a slow-moving frontal boundary.
