Recent Korea Meteorological Administration forecasts and supporting model runs indicate a daytime high of 30–31°C for Incheon on August 28, with mostly cloudy skies, scattered showers or thunderstorms, and moderate southerly winds likely moderating peak readings. Persistent regional heat and elevated dew points support the upper end of that range, yet widespread cloud cover and precipitation reduce the chance of 32°C or higher. Historical August baselines near 30°C align with current conditions, while ensemble spread in global models introduces modest uncertainty around exact maxima; traders have priced this narrow band most heavily given the short time to resolution.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
