Recent KMA forecasts for Incheon/Seoul on August 18 show a minimum near 25°C under clearing skies after showers through the 17th, with highs reaching 32–33°C amid persistent warm, humid summer air. The tight 42.5%–37.5% split between 24°C and 25°C reflects model sensitivity to overnight cloud cover, boundary-layer moisture, and radiational cooling rates following the recent rain, as clearer conditions could shave a degree while residual humidity and urban heat limit further drops. Historical August lows average 22–24°C, but the current pattern favors the upper end. Updated KMA model runs and observations in the next 48 hours will likely narrow the range.

This market will resolve based on the lowest 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 lowest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
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 KMA forecasts for Incheon/Seoul on August 18 show a minimum near 25°C under clearing skies after showers through the 17th, with highs reaching 32–33°C amid persistent warm, humid summer air.
