As people return to their daily routines on Monday morning, light rain is expected primarily in the metropolitan area. With a temperature difference between day and night reaching up to 15 degrees Celsius, it is advisable to bring outerwear.


According to the Korea Meteorological Administration, light rain of less than 0.1 mm is anticipated in the metropolitan area, inland and mountainous regions of Gangwon, northern Chungcheong, and Jeju Island until 9 a.m. tomorrow.


Fog with visibility of less than 1 km may occur in the inland areas of Gyeonggi, Gangwon, Chungcheong, Jeonbuk, and Gyeongbuk from early morning to the morning hours.


The weather agency forecasts a temperature difference of 10 to 15 degrees Celsius between day and night. Morning lows are expected to range from 14 to 20 degrees Celsius, while daytime highs will fluctuate between 25 and 29 degrees Celsius.


Expected morning lows in major cities are as follows: Seoul 18°C, Incheon 18°C, Suwon 18°C, Chuncheon 16°C, Gangneung 18°C, Daejeon 17°C, Cheongju 18°C, Gwangju 18°C, Jeonju 18°C, Busan 21°C, Ulsan 19°C, Daegu 19°C, and Jeju 22°C.


Daytime highs are forecasted to be: Seoul 26°C, Incheon 25°C, Suwon 25°C, Chuncheon 26°C, Gangneung 26°C, Daejeon 26°C, Cheongju 26°C, Gwangju 28°C, Jeonju 26°C, Busan 28°C, Ulsan 28°C, Daegu 28°C, and Jeju 27°C.


Air quality is expected to be at a 'good' to 'moderate' level across all regions. However, some areas in the central-western region, including Seoul, Incheon, southern Gyeonggi, and Chungnam, may experience a 'moderate' level of fine dust due to the accumulation of domestically generated pollutants from stagnant air and converging air currents.
