It will be very warm during the Lunar New Year holidays.
If you pay attention only to the large daily temperature difference, there will be no big inconvenience due to the weather, but it seems that thick fog will often occur, so you need to move more carefully than usual on your way home.
From the night of today (10th), there will be a thick fog with a visibility distance of 200m or less centering on the west coast and central inland.
From dawn to morning, the line of sight will be further narrowed.
There will be many places where the fog remains in a pale form tomorrow, and tomorrow's daytime temperatures will rise to 10 degrees in Seoul, 15 degrees in Gwangju, and 13 degrees in Daegu.
On Lunar New Year's day, the temperature will rise and warmth will be felt, but fine dust will start accumulating from the west, and air quality in most regions of the country will become cloudy on weekends.
On the last day of the holiday, there is also rain news in Jeonnam and Gyeongnam, so you should refer to it.
