On Constitution Day, July 17, the weather across the country is expected to be mostly cloudy, with rain beginning in various regions this afternoon. Due to the influence of a stationary front, the Chungcheong region, southern areas, and Jeju Island will experience cloudy conditions or rain, with precipitation expected to expand to the capital region and Gangwon Province by night.


According to the Korea Meteorological Administration, the country will be under the influence of a high-pressure system moving eastward from the Bohai Sea near China. Rain is forecasted to continue until July 19 as the stationary front moves northward.

Some areas in the central region may experience very heavy rain of 50 to 80 mm per hour.


Despite the rain, the perceived temperature is not expected to drop significantly. Most regions will continue to experience high humidity, with maximum perceived temperatures around 31 degrees Celsius.


The morning low is expected to range from 23 to 26 degrees Celsius, while the afternoon high will be between 29 and 32 degrees Celsius.
