On September 27, 2026, the nationwide air quality for fine dust is forecast to be "Good."
According to the Korea Environment Corporation’s forecast overview, all regions are expected to be rated “Good” to “Moderate.”
Regarding the causes, the agency analyzed, “In some central and western regions, domestically generated fine dust will accumulate in the morning and at night due to atmospheric stagnation and airflow convergence, causing concentrations to rise; however, concentrations will decrease during the day due to smooth vertical (upper and lower layers) dispersion, so the daily average concentration is expected to be ‘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)
