Fall is drawing closer across Korea, with cool mornings and warmer afternoons bringing wide temperature swings Friday.
As of 9 a.m., morning temperatures ranged from 10 to 15 degrees Celsius in northern parts of South Korea and from 15 to 20 C in southern regions, according to the Korea Meteorological Administration.
Daytime highs were forecast at 24 to 29 C, close to seasonal averages of 24 to 28 C.
"Morning temperatures dropped as cold air moved into Korea along the edge of a high-pressure system traveling from northeastern China toward the northern East Sea," a KMA official said.
The cooler temperatures brought dense fog to inland and mountainous areas of Gangwon Province, reducing visibility to less than 200 meters in some places.
Fog also formed in northern and southeastern Gyeonggi Province, inland North and South Chungcheong provinces and North Jeolla Province, making it difficult to see beyond 1 kilometer.
Sea levels are expected to remain higher than usual for the time being due to the moon's gravitational pull.
Winds of 30 to 55 kilometers per hour are set to sweep the far offshore waters south of Jeju Island throughout the day, with waves reaching 1.5 to 3.5 meters.
Fine dust levels are forecast to remain "good" nationwide.
