Weekend, Cold Arriving Over Ten Days Early... Lowest Temperatures This Fall in Seoul and More

Morning temperatures 0~11°C, 3~8°C lower than yesterday... Daytime highs 14~20°C

On Saturday morning, the 21st, temperatures ranged from 0 to 11 degrees Celsius, dropping 3 to 8 degrees compared to the previous morning (2 to 13 degrees) and significantly lower than the typical temperatures for this time of year (5 to 14 degrees). Such morning temperatures usually occur in early November.

At 7 a.m., temperatures in major cities were as follows: Seoul 7.7°C, Incheon 13.3°C, Daejeon 4.1°C, Gwangju 8.6°C, Daegu 5.9°C, Ulsan 7.3°C, and Busan 9.8°C. The wind was quite strong, making the perceived temperature feel lower than the actual temperature. A cold northwesterly wind blew along the edge of a high-pressure system located near Shanghai, China. Due to the high pressure, the sky was clear overnight, allowing for strong radiational cooling, which caused temperatures to drop sharply.

At Seoraksan in Gangwon Province, the temperature dropped to minus 5.6°C around 12:30 a.m., marking the lowest temperature this fall at Seoraksan. In the inland and mountainous areas of Gangwon, as well as northern and eastern parts of Gyeonggi Province, temperatures fell below zero, and snow likely fell in the higher mountainous regions. In fact, the first snow of the fall season fell on Seoraksan that day. Compared to last year, the first snow at Seoraksan was 11 days later.

In Seoul, the temperature dropped to 5.9°C around 4 a.m., the lowest this fall. In Bukchuncheon (Udu-dong, Chuncheon-si, Gangwon), the first frost and first ice of the fall were observed that day. The first frost also occurred in Daejeon and Andong, Gyeongbuk. Although these first frost and ice occurrences were later than last year, they were earlier than the average year. The highest temperature during the day is expected to be between 14 and 20 degrees Celsius. With sunshine, daytime temperatures will rise, causing a significant temperature difference of about 10 to 15 degrees Celsius, especially inland.

Strong winds with instantaneous gusts of 70 km/h (90 km/h in mountainous areas) will blow along the west coast, southern coast of Jeonnam (some parts), and Jeju until the morning. Other regions will experience strong winds with gusts around 55 km/h (70 km/h in mountainous areas). Due to the west-high, east-low pressure system, persistent westerly winds will blow, drying out the air as they cross mountain ranges. The Gangwon Yeongdong region, which faces these dry westerly winds, will experience dry atmospheric conditions, so caution is advised to prevent fires.

Regarding the seas, strong winds of 35 to 60 km/h (10 to 16 m/s) will blow until the morning over the West Sea, southern offshore waters of the South Sea (excluding the eastern offshore waters), central offshore waters of the East Sea, and around Jeju. Winds will continue until night over the eastern offshore waters of the East Sea and until early morning on the 22nd over the outer offshore waters of the East Sea. Waves will rise to heights of 2 to 4 meters. Swells will continue to flow into the East Coast until the 22nd, bringing high waves ashore.
