Air quality for fine particulate matter nationwide is forecast to be "Good" on September 30, 2026.
According to the Korea Environment Corporation’s forecast overview, all regions are expected to be rated “Good” to “Moderate.”
Regarding the causes, the report states, “In some western regions, concentrations of domestically generated fine dust are expected to rise through the morning due to atmospheric stagnation and airflow convergence; however, concentrations will decrease in the afternoon due to favorable atmospheric dispersion. At night, “Moderate” levels of foreign fine dust will flow in along northwesterly air currents, resulting in an expected daily average concentration of “Moderate.”
Since fine dust concentrations will not be high across all regions, there should be no significant disruption to outdoor activities.
Good — Seoul, Jeju, South Jeolla, North Jeolla, Gwangju, South Gyeongsang, North Gyeongsang, Ulsan, Daegu, Busan, South Chungcheong, North Chungcheong, Sejong, Daejeon, Yeongdong, Yeongseo, Southern Gyeonggi, Northern Gyeonggi, Incheon (19 locations)
