Recent Korea Meteorological Administration forecasts highlight scattered afternoon showers over Seoul and Incheon on August 17, with 60% precipitation probability that could limit peak heating through cloud cover and evaporative cooling. This aligns with the tight market clustering around 28–29°C, as convective timing and intensity remain the key variables separating those outcomes from a 30°C high. Ensemble guidance shows typical late-summer humidity supporting modest instability without strong advection of warmer air, while historical August baselines near 30°C provide context for why traders assign lower weight to extremes. Updated model runs and official briefings before resolution will refine these temperature thresholds.

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 17 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.
