Recent Korea Meteorological Administration (KMA) aviation forecasts for Seoul-area airports project highs of 12°C at Incheon and 16°C at Gimpo on April 5 amid mostly cloudy conditions from an advancing frontal boundary, fueling trader consensus with 12°C (24%) and 13°C (21.5%) leading closely. Over the past 48 hours, GFS and ECMWF model ensembles have converged on this cooler cluster—down sharply from earlier warmer runs—due to northerly winds ushering cooler air masses and persistent cloud cover following April 2's observed 13-14°C peak. A 2-3°C spread persists from uncertainties in frontal timing, precipitation spillover from April 4 rains, and low-level temperature advection. Daily KMA updates and new model cycles will refine probabilities as resolution nears.

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.
