[Suwan News = Environmental Correspondent] As of April 4, 2026, fine dust air quality across the country is at the “Good” level.
According to the general forecast overview, all regions are expected to range from “Good” to “Moderate.” However, late at night, the Seoul Metropolitan Area, the western part of Gangwon Province, the Chungcheong region, Gwangju, and North Jeolla Province are expected to reach “Poor” levels.
Regarding the causes of these air quality conditions, “Concentrations remained low in most areas through the day due to the cleansing effect of precipitation and smooth atmospheric dispersion. However, starting in the late afternoon, ‘Moderate’ levels of foreign fine dust were carried in by northwesterly winds and accumulated overnight due to stagnant air, causing concentrations to rise in most western regions. As a result, the daily average concentration is expected to be ‘Moderate’ in most central regions, while other regions are expected to be ‘Good.’” Detailed PM2.5 ratings for major regions nationwide were observed as follows.
Seoul: Moderate, Jeju: Good, South Jeolla: Good, North Jeolla: Good, Gwangju: Good, South Gyeongsang: Good, North Gyeongsang: Good, Ulsan: Good, Daegu: Good, Busan: Good, South Chungcheong: Moderate, North Chungcheong: Good, Sejong: Good, Daejeon: Good, Yeongdong: Moderate, Yeongseo: Moderate, Southern Gyeonggi: Moderate, Northern Gyeonggi: Moderate, Incheon: Moderate
