Recent Korea Meteorological Administration forecasts point to a 34°C high for Incheon on August 11 amid a persistent heatwave driven by a strong subtropical high-pressure ridge and weak steering flow that limits cooling. Traders have priced the 33°C and 32°C outcomes highest because model ensembles show modest uncertainty from possible increased cloud cover, light northerly winds, or an earlier-than-expected marine influence that could cap afternoon maxima near the coast. Recent days recorded 34–35°C peaks under similar synoptic conditions, yet slight easing noted in weekend guidance and historical variability in urban heat-island effects versus airport observations create the narrow spread around 32–34°C. Updated model runs and official briefings over the next 24 hours will likely refine these probabilities.

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 11 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.
