Recent official forecasts from the Korea Meteorological Administration and international models indicate overnight lows in Seoul-Incheon around 24–26°C for August 9 amid an active heat wave emergency affecting much of the peninsula. Persistent high pressure and weak winds have suppressed cooling, keeping minimum temperatures elevated relative to historical August averages of roughly 22–24°C. Ensemble guidance shows limited spread, with the strongest consensus clustering near 25°C, while any cloud cover or brief showers could nudge readings slightly lower. Updated model runs and KMA briefings through August 8 will provide the final inputs before market 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 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.
