Recent Korea Meteorological Administration short-range guidance for August 19 points to a daytime maximum near 33 °C under partly to mostly cloudy skies, yet trader consensus clusters tightly around 29–30 °C. Differentiation among these closely matched outcomes hinges on the precise evolution of cloud cover and any scattered showers that could reduce incoming solar radiation and limit afternoon heating. Higher humidity and light northeasterly flow typical of late-summer monsoon remnants further modulate the realized high by enhancing evaporative cooling. Updated model runs over the next 48 hours, particularly afternoon convective trends and boundary-layer moisture profiles, will determine whether temperatures reach the upper end of guidance or remain capped near the historical late-August average of 29–31 °C.

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 19 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.
