Recent official forecasts from the Korea Meteorological Administration indicate mostly cloudy skies with periods of rain on August 21 in the Seoul-Incheon area, pointing to a minimum temperature near 25°C. This aligns with the closely matched market-implied odds favoring 24°C (46%) or 25°C (39%), as persistent cloud cover and precipitation limit overnight radiative cooling compared to clearer conditions. Regional humidity near 80% and light winds further moderate temperature drops, while the broader late-August pattern—following earlier heatwave influences from easterly flows and distant typhoon effects—shows a slight cooling trend from seasonal averages of 22–23°C. Minor model variations in rain timing or wind shifts could tip the minimum between these thresholds ahead of final observations.

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 21 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.
