‘(Seoul=Yonhap News) Reporter Lee Jaeyoung = The severe cold starts on Tuesday, the 30th.’,

‘On the 29th, cold air will move south following the pressure trough that brought rain and snow to the central region, supporting the development of continental high pressure to the northwest of Korea. Cold air will flow into Korea from the northwest along the edge of this high pressure from late night.’,

‘As a result, temperatures will drop sharply overnight.’,

‘The morning low on the 30th will be -8 to 3°C, which is higher than the average temperatures for this time of year but 5 to 10 degrees lower than the morning low of the 29th (-4 to 8°C).’,

‘The daytime high on the 30th will be 0 to 9°C, significantly lower than the 29th (7 to 15°C).’,

‘The expected minimum and maximum temperatures in major cities are -3°C and 2°C in Seoul, -4°C and 2°C in Incheon, -3°C and 4°C in Daejeon, -1°C and 6°C in Gwangju, -1°C and 7°C in Daegu, 1°C and 8°C in Ulsan, and 3°C and 9°C in Busan.’,

‘This cold spell will continue from the end of the year into the beginning of the new year.’,

‘On the morning of the last day of 2025, the lowest temperature will be -12 to -1°C, and the highest temperature will be -5 to 4°C. On the first day of 2026, the morning low and day high are expected to be -16 to -4°C and -6 to 4°C.’,

‘Early to mid-January is usually the coldest period of the year. The effect of reduced sunlight as the day length grows shorter until the winter solstice (December 20 this year) appears later due to the specific heat of the surface and the atmosphere.’,

‘The northwest wind causing this cold is clean, pushing away fine dust.’,

“On the 29th, the air quality was poor, with an ultrafine dust advisory issued for the Seoul Metropolitan Area and Chungnam. However, on the 30th, the nationwide fine dust concentration is expected to be ‘good’ or ‘average’.”,

“Nevertheless, fine dust levels will be ‘poor’ in Seoul, southern Gyeonggi, Daejeon, Sejong, and Honam in the early morning, in Jeju in the early morning, and in the Gangwon Yeongseo, Chungbuk, and Yeongnam areas until the morning, so caution is needed.”,

‘A dry weather advisory has been issued for the eastern coastal areas of Gangwon, inland mountain areas in the south, and North and South Gyeongsang coastal areas including Busan and Ulsan due to dry conditions. With strong winds of up to 55 km/h (70 km/h in mountainous areas) expected in eastern Gangwon until the 30th, the risk of large fires, such as wildfires, increases. Caution is necessary to prevent fires.’,

‘From the night of the 29th, strong winds of 30~60 km/h (8~16 m/s) and high waves of 1~4 m are expected in the far northern and southern parts of the East Sea, so caution is advised when navigating or fishing.’,
