Official observations from the Korea Meteorological Administration at Incheon International Airport recorded a minimum temperature of 23°C during the early morning hours of August 9, 2026, under clear to partly cloudy conditions with light northeasterly winds. This aligns with short-range forecast guidance projecting overnight lows near 24°C that were refined by real-time station data, establishing 23°C as the daily minimum. The 100% market-implied probability reflects this verified reading, as the lowest temperature is typically captured between 3 AM and 9 AM local time. A realistic challenge would require a post-event data revision or station anomaly, though standard quality controls make significant shifts improbable at this stage.

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 9 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.
