On Friday, September 11, morning temperatures will be cooler than usual, but they are expected to rise significantly during the day, leading to a temperature variation of around 15 degrees Celsius in some areas.
According to the Korea Meteorological Administration, the morning low in Seoul will be 15 degrees Celsius, while in Paju it will be 13 degrees, about 3 degrees lower than the average. In Gangwon's Daegwallyeong, morning temperatures are expected to drop to single digits.
Conversely, temperatures will rise quickly during the day. The high in Seoul will reach 28 degrees Celsius, while Suwon will see a high of 27 degrees. In the southern regions, Daegu and Busan will also hit 28 degrees, and Gwangju will reach 29 degrees, with most areas exceeding 25 degrees. Andong will experience a significant increase from a morning low of 13 degrees to much warmer afternoon temperatures, resulting in a large temperature difference between day and night, particularly inland.
The skies across the country will be partly cloudy, with strong sunlight expected to break through the clouds. The ultraviolet index is forecasted to be at a 'high' to 'very high' level in most regions.
A wave warning has been issued for the southern coast and Jeju waters, where strong winds and high waves are anticipated. Coastal areas may experience swells, raising concerns about flooding in low-lying areas and safety incidents.
The large temperature variations characteristic of autumn will continue into the weekend, with rain expected in the mountainous regions of Jeju on Sunday.
