On the 4th, when the new president takes office, the weather will be mostly clear nationwide, with a temperature difference of around 15 degrees between day and night, especially in the southern inland regions.

The Korea Meteorological Administration forecasted that the temperature on this day would be similar to the average (minimum 13–17 degrees, maximum 23–28 degrees).

The day will be clear across the country due to the influence of a high pressure system moving east from near Shanghai, China.

The daytime temperature will rise above 25 degrees, particularly in the southern regions, and the temperature difference will be around 15 degrees, so health management should be a priority.

The morning minimum temperature will be between 11 and 17 degrees, while the maximum temperature during the day will be between 21 and 28 degrees.

The expected minimum temperatures in major cities are ▲Seoul 15 degrees ▲Incheon 16 degrees ▲Chuncheon 12 degrees ▲Gangneung 17 degrees ▲Daejeon 15 degrees ▲Daegu 14 degrees ▲Jeonju 14 degrees ▲Gwangju 15 degrees ▲Busan 16 degrees ▲Jeju 18 degrees.

The maximum temperatures are expected to be ▲Seoul 24 degrees ▲Incheon 21 degrees ▲Chuncheon 24 degrees ▲Gangneung 26 degrees ▲Daejeon 26 degrees ▲Daegu 28 degrees ▲Jeonju 26 degrees ▲Gwangju 27 degrees ▲Busan 26 degrees ▲Jeju 26 degrees.

Fine dust levels are expected to be 'good' across all regions.
