On Tuesday, October 13, autumn rain is expected to sweep across the country, bringing an end to an unusual late summer heat wave. After the rain, cold air from the north will significantly lower temperatures.
According to the Korea Meteorological Administration, rain that began late on October 12 in the Seoul metropolitan area, Chungcheong, and western South Gyeongsang Province will expand nationwide on the 13th. The rain is expected to taper off by midday, although some areas in South Gyeongsang may experience rain into the late afternoon.
Forecasts indicate precipitation amounts of 10 to 50 mm in the Seoul metropolitan area, inland and mountainous regions of Gangwon, and Chungcheong; 5 to 50 mm in Gwangju and South Jeolla; and 5 to 40 mm in North Jeolla, Busan, Ulsan, South Gyeongsang, Daegu, North Gyeongsang, Ulleungdo, and Dokdo. Jeju Island is expected to receive heavy rain, with amounts exceeding 80 mm in mountainous areas (averaging 10 to 60 mm).
The record-breaking high temperatures experienced in October will subside with the rain. On October 12, warm and humid southerly winds pushed temperatures to 30.1 degrees in Seoul and 31.5 degrees in Daejeon, setting new records for October across various regions.
On the morning of October 13, the lowest temperatures will range from 15 to 20 degrees, which is above average, but daytime highs will return to normal levels, ranging from 20 to 26 degrees.
Expected temperatures in major cities (low to high) are as follows: Seoul, Incheon, and Daejeon 17-22 degrees; Gwangju and Ulsan 18-24 degrees; Daegu 17-24 degrees; and Busan 20-24 degrees. Notably, after the pressure system moves out, temperatures are expected to plummet to between 5 and 14 degrees by the morning of Wednesday, October 14.
Meanwhile, from the night of October 13, strong winds with gusts of up to 55 km/h (70 km/h in mountainous areas) are expected to affect the west coast and Gangwon, with warnings for vessels at sea as wave heights will gradually increase starting from the central West Sea.
