On Tuesday, the 1st, the weather will be mostly clear nationwide, with significant temperature differences expected. The morning low temperature is forecasted to be between -2 and 6 degrees, while the daytime high is expected to be between 13 and 18 degrees.

From early morning to morning, frost may occur mainly in inland areas nationwide, so care should be taken for crop management and to prevent damage to flowering fruit trees. In particular, on roads near bridges (such as Yeongjong Bridge, University of Incheon Bridge, and Western Sea Bridge) as well as near rivers, lakes, and valleys, thick fog is expected, so caution should be exercised to prevent vehicle collisions.

The fine dust concentration will be 'bad' in the metropolitan area, while other regions will show levels ranging from 'good' to 'moderate.' Sejong, Chungcheongnam-do, Gwangju, and North Jeolla Province are expected to be 'bad' in the morning, while the western Gangwon and Chungcheong regions will temporarily experience 'bad' levels at night.

The waves in the sea will be between 0.5 and 1.0 meters in the East Sea and South Sea, and between 0.5 and 1.5 meters in the West Sea. The wave height in the outer sea (about 200 km from the coastline) is expected to be between 0.5 and 1.5 meters in the East Sea, West Sea, and South Sea.
