This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 21 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).

Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.

"context_description": "Korea Meteorological Administration observations show Seoul's temperatures peaking at 14°C so far on April 21, 2026, under mostly cloudy skies and a cold wave advisory affecting nearby regions, driving the market's 99.8% implied probability on this outcome as trader consensus reflects real-time data from official stations. Current readings hover around 11°C midday with light winds limiting solar heating, while short-range forecast models converge on no further intensification due to persistent cloud cover and cold air advection from the north. Historical April highs average 18°C, but this anomalously cool spell—2–4°C below normal—stems from recent frontal passage. A realistic challenge would require prolonged clear skies and stronger insolation this afternoon, though updated KMA hourly data expected through evening make exceeding 14°C improbable.",
