On Sunday, the 17th, the daytime high temperatures in most areas nationwide are forecasted to be between 28 to 35 degrees Celsius, and a heat wave warning will remain in effect. However, there may be some places in the metropolitan area and other regions where raindrops will fall.
As of 5 a.m. that day, the temperatures were: Seoul 26.2 degrees, Incheon 25.6 degrees, Suwon 24.4 degrees, Chuncheon 22.8 degrees, Gangneung 28.3 degrees, Cheongju 25.1 degrees, Daejeon 23.6 degrees, Jeonju 24.2 degrees, Gwangju 23.9 degrees, Jeju 25.7 degrees, Daegu 24.3 degrees, Busan 26.6 degrees, Ulsan 24.1 degrees, and Changwon 24.5 degrees.
In the metropolitan area (excluding southern Gyeonggi) and inland and mountainous areas of northern and central Gangwon, rain will fall at times from morning until night. In southern Gyeonggi and inland and mountainous areas of southern Gangwon, there may be some places with less than 0.1 mm of rain in the morning.
Thick fog is likely to occur until morning in the inland areas of Gangwon, Chungbuk, Jeolla region (excluding the western coastline of Jeonbuk), and inland Gyeongnam. Roads near bridges on the coast and near rivers, lakes, or valleys inland will have denser fog compared to surrounding areas, so caution should be exercised for traffic safety.
Vessels navigating or fishing should be cautious of maritime safety accidents, and those using maritime traffic are advised to check operating information in advance.
Also, until the morning, strong winds may blow in Gangwon Yeongdong at moments with wind speeds around 55 km/h (15 m/s) (70 km/h or 20 m/s in mountainous areas), so attention should be paid to facility management.
The concentration of fine dust is expected to be at a level of 'good' to 'moderate' across all regions due to smooth atmospheric dispersal.
The waves at sea will be 0.5 to 1.0 meters in the East Sea and West Sea, and 0.5 meters in the South Sea.
The wave heights in the offshore waters (about 200 km from the coastline) are expected to be 0.5 to 1.5 meters in the East Sea and West Sea, and 0.5 to 1.0 meters in the South Sea.
