The morning low temperatures are forecasted to be between -2 and 6 degrees Celsius, and the daytime highs between 13 and 18 degrees Celsius. From dawn to morning, frost is expected in inland areas nationwide, so caution is needed for crop management and damage to fruit trees during the blooming period.

Especially on bridges located on the coast (Yeongjong Bridge, Incheon Bridge, Seohae Bridge, etc.) and roads adjacent to rivers, lakes, and valleys, dense fog is expected, so traffic safety should be observed to prevent vehicle collisions.

Fine dust levels will be 'bad' in the Seoul metropolitan area and 'good' to 'moderate' in other regions.

Sejong, Chungnam, Gwangju, and Jeonbuk are expected to have 'bad' levels in the morning, and Gangwon Yeongseo and the Chungcheong region may experience temporarily 'bad' levels at night.

Sea waves will be 0.5 to 1.0 meters in the East Sea and South Sea coastal waters, and 0.5 to 1.5 meters in the West Sea coastal waters.

Wave heights in the offshore waters (about 200 km from the coastline) are expected to be 0.5 to 1.5 meters in the East Sea, West Sea, and South Sea.
