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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent Korea Meteorological Administration forecasts project a mostly cloudy day with 30% precipitation chances and a daytime maximum near 32°C for Incheon-Seoul on August 15, following an early-August regional heatwave that elevated baseline temperatures. Trader consensus clustering around 29–30°C reflects uncertainty from variable cloud cover that can reduce surface insolation and limit peak heating, alongside possible light showers and light easterly winds that enhance mixing in the marine boundary layer. Differentiation among these tightly spaced outcomes hinges on exact diurnal timing of thicker clouds or convective activity, which models show can shift the daily high by 1–2°C. Updated KMA guidance and ensemble runs ahead of resolution will clarify these variables for active positions.
