On August 20, 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 most central and western regions, concentrations of domestically generated fine dust are expected to rise in the morning and at night due to atmospheric stagnation, but concentrations will decrease in the afternoon due to vertical (upper and lower layer) dispersion, resulting in a 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.
Moderate — Seoul, Southern Gyeonggi (2 areas)
Good — Jeju, South Jeolla, North Jeolla, Gwangju, South Gyeongsang, North Gyeongsang, Ulsan, Daegu, Busan, South Chungcheong, North Chungcheong, Sejong, Daejeon, Yeongdong, Yeongseo, Northern Gyeonggi, Incheon (17 areas)
