Recent KMA guidance and ensemble models indicate a maximum near 30–32 °C at the Incheon station on August 15 under persistent cloud cover and a 30 % chance of showers, which limits solar heating and caps afternoon peaks. High humidity and light northeasterly flow maintain heat indices above 33 °C even if the dry-bulb reading stays modest, while historical August climatology for the region centers on 29–31 °C. Trader consensus clusters at 29–30 °C because updated short-range runs favor greater cloudiness than earlier guidance, narrowing the window for 31 °C or higher. Resolution hinges on the official 24-hour maximum reported by KMA, with any late-day clearing the key variable that could shift the outcome.

This market will resolve based on the highest 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 highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 15 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest 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.
