Recent KMA forecasts for August 15 indicate a maximum near 32°C in Incheon under mostly cloudy skies with 20–30% precipitation chances and moderate humidity, driving the market's tight clustering around 29–31°C. Following an earlier August heatwave that produced peaks near 39°C, current conditions reflect stabilizing high pressure with potential afternoon convection that could cap temperatures slightly below model guidance. Short-range ensemble variability and steering influences introduce modest uncertainty, while historical August baselines near 30–31°C provide context. Updated KMA model runs and real-time observations on the 14th–15th will refine these probabilities ahead of resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 15 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Incheon Intl Airport Station, available here: https://www.wunderground.com/history/daily/kr/incheon/RKSI.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
