Latest ensemble forecasts from global models like ECMWF and GFS, corroborated by the Korea Meteorological Administration, project Seoul's March 27 high temperature clustering around 15°C, fueling its 36% implied probability as traders price in a mild high-pressure ridge over the Korean Peninsula. This edges out 16°C or higher at 32.5% amid model spread reflecting uncertainties in cloud cover and southerly winds, which could push peaks upward by 1-2°C. Historical data shows March 27 maxima averaging 12°C since 1991, but an anomalously warm early spring—driven by transient Arctic Oscillation shifts—elevates warmer outcomes over cooler ones like 9-14°C, despite 16.5% odds each, as diurnal heating thresholds differentiate tight races. Traders eye tomorrow's 12Z updates for resolution catalysts.

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.
