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 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Incheon Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Korea Meteorological Administration observations confirm Seoul's daytime high temperature reached 12°C on April 11 amid an untimely cold snap, with northerly winds and persistent cloud cover capping insolation and suppressing readings well below the seasonal April average of 18°C. Hourly data shows peaks around midday at 12–14°C before cooling to 11°C by evening under mostly cloudy skies, aligning with model consensus from short-range forecasts that factored in a lingering cold air mass. Trader consensus at 99.9% implied probability reflects this observational lock-in, as sunset nears with minimal solar heating potential. Realistic challenges—sudden clearing or measurement revisions—are improbable given current atmospheric stability and diurnal cooling trends, though final KMA daily summary will confirm resolution.
