This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 18 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's latest short-range forecasts project Seoul's highest temperature on April 18 around 21-23°C under persistent high-pressure ridging and clear skies, driving trader consensus to 64.5% implied probability for 21°C or higher.** Recent observations confirm above-average warmth, with April 15-16 highs reaching 19-21°C amid southerly flows and minimal cloud cover, aligning with global model ensembles like ECMWF and GFS showing continued mild advection. Mid-April climatology averages 17-19°C highs, but current upper-air patterns favor 2-4°C boosts; lower outcomes like 20°C (14%) reflect uncertainty from possible afternoon clouds or weak fronts. Updated guidance expected April 17 could refine trajectories as resolution nears.
