On Wednesday, the 30th, the weather will start mostly clear across the country but will gradually become overcast, particularly in the central regions. Rain is expected to begin in the northern inland areas of Gyeonggi and northern Gangwon from the afternoon, expanding to include Seoul and the surrounding metropolitan area, as well as the inland and mountainous regions of Gangwon by late afternoon. By night, rain will also reach parts of Chungcheong and Jeonbuk.


The anticipated rainfall amounts are 5 to 20mm in northeastern Gyeonggi, the five western islands, and northern inland Gangwon. In Seoul, Incheon, Gyeonggi, and the inland and mountainous areas of Gangwon, 5 to 10mm is expected, while Daejeon, Sejong, Chungnam, Chungbuk, and Jeonbuk are forecasted to receive less than 5mm.


Morning low temperatures are predicted to be between 12 and 18 degrees, with daytime highs ranging from 24 to 28 degrees. There will be a significant temperature difference between day and night, particularly in inland areas, so residents should take care of their health. In Seoul, the morning temperature will be 16 degrees, rising to 25 degrees during the day, while Daegu and Ulsan could see highs of 28 degrees.


In areas where rain falls in the afternoon, visibility may decrease for short periods, and roads could become slippery. Especially during the evening commute, rain is expected in the metropolitan area and inland Gangwon, so caution is advised for traffic safety. In regions without rain, mornings will be cool, and temperatures will rise significantly during the day, so it is advisable to prepare light outerwear.


Fine dust levels are expected to be at 'good' to 'moderate' levels nationwide. Sea waves will reach 0.5 to 1.5 meters in the East and West Seas, and 0.5 to 1.0 meters in the South Sea.
