Official forecasts from the Korea Meteorological Administration (KMA) place the minimum temperature for Seoul and Incheon at 25°C on August 19, driven by overnight cloud cover and scattered showers that limit radiational cooling under humid late-summer conditions. This aligns with regional model consensus and typical August climatology, where morning lows average near 23–25°C amid persistent moisture and weak easterly flow. The 100% market-implied probability reflects traders' confidence in these verified observational thresholds and station measurements. A realistic challenge could arise only from an unexpected clear-sky nocturnal cooling event or localized urban heat-island effects pushing readings slightly lower, though current guidance shows low likelihood of deviation before resolution.

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 19 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.
