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 16 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 forecasts from agencies including the Korea Meteorological Administration and Met Office indicate a maximum of 29–30°C in Incheon on August 16, with partly cloudy skies, light easterly winds, and moderate humidity moderating peak readings after early August's extreme heatwave. Coastal Incheon's maritime influence typically caps temperatures 1–2°C below inland Seoul sites, while variable afternoon cloud cover and potential sea-breeze effects introduce uncertainty around the exact daily high. Traders' near-even split between 29°C and 30°C reflects model consensus on these thresholds amid typical late-summer variability, with higher outcomes like 31°C or 33°C discounted unless clearer skies develop. Updated model runs and official briefings over the next 48 hours will refine resolution around the 9 AM–5 PM peak window.
