On August 19, 2026, the nationwide air quality for fine particulate matter is forecast to be "Good."
According to the Korea Environment Corporation’s forecast overview, all regions are expected to range from “Good” to “Moderate.”
Regarding the causes, the agency analyzed, “In most central and western regions, domestically generated fine dust will accumulate due to stagnant air in the morning and at night, causing concentrations to rise; however, concentrations are expected to decrease in the afternoon due to vertical (upper and lower layers) dispersion, resulting in a daily average concentration of ‘Moderate.’”
Since PM2.5 concentrations will not be high across all regions, there should be no significant disruption to outdoor activities.
Moderate — Seoul, Southern Gyeonggi, Northern Gyeonggi, Incheon (4 regions)
Good — Jeju, South Jeolla, North Jeolla, Gwangju, South Gyeongsang, North Gyeongsang, Ulsan, Daegu, Busan, South Chungcheong, North Chungcheong, Sejong, Daejeon, Yeongdong, Yeongseo (15 regions)
