Until the afternoon (12:00-18:00), some parts of the Seoul metropolitan area may experience less than 0.1 mm of light rain. In the inland and mountainous areas of Gangwon and northern North Chungcheong, there may be either less than 0.1 mm of light rain or less than 0.1 cm of snow flurries.

Until the morning, icy patches may form on roads in central regions (excluding Yeongdong, Gangwon), so caution is advised.

The atmosphere will be very dry, especially along the east coast and mountainous areas of Gangwon, and the east coast and northeastern mountainous regions of North Gyeongsang, where dry weather advisories are in effect. Strong winds are also expected, so special attention is needed to prevent wildfires and other fires.

Waves will range from 0.5 to 1.5 meters in the coastal waters of the East and West Seas, and from 0.5 to 1.0 meters in the coastal waters of the South Sea. In the offshore areas (up to about 200 km from the coastline), wave heights are expected to be 0.5 to 3.5 meters in the East Sea, 0.5 to 2.0 meters in the West Sea, and 0.5 to 1.5 meters in the South Sea.
