On Chuseok, the 25th, the weather across the country is expected to be mostly cloudy, making it difficult to view the full moon. Rain is forecasted to begin in the morning along the eastern coast and mountainous regions of Gangwon, spreading to central and southern areas in the afternoon.

According to the Korea Meteorological Administration, rain is expected to start in the morning, primarily affecting the eastern coast and mountainous areas of Gangwon, with some precipitation also anticipated in central regions and parts of North and South Jeolla.

Expected rainfall amounts vary by region: approximately 5 mm in Seoul, Incheon, and Gyeonggi; 5 to 10 mm in Daejeon, Sejong, Chungnam, and Chungbuk; 20 to 60 mm along the coast of South Jeolla; 10 to 40 mm in Gwangju and inland South Jeolla; 5 to 20 mm in North Jeolla; and around 5 mm in Daegu and North Gyeongsang.

Morning low temperatures are expected to range from 14 to 21 degrees Celsius, with daytime highs projected between 23 and 28 degrees.

Fog is expected in southeastern Gyeonggi, inland Gangwon, Chungnam, eastern North Jeolla, and inland North Gyeongsang during the morning, so caution is advised.

Waves in the East and South Seas are expected to reach 0.5 to 1.5 meters, while the West Sea will see waves of about 0.5 meters. In the offshore waters (approximately 200 km from the coastline), wave heights are forecasted to be 0.5 to 2.0 meters in the East Sea, 0.5 to 1.0 meters in the West Sea, and 0.5 to 1.5 meters in the South Sea.
