On August 28, 2026, the nationwide air quality for ultrafine particulate matter is forecast to be "Good."
According to the Korea Environment Corporation’s forecast overview, all regions are expected to be rated “Good.”
Regarding the cause, "Due to atmospheric stagnation, fine dust from the previous day will linger, resulting in 'Moderate' air quality in most central and western regions until the morning. However, starting in the afternoon, the inflow of clean southerly air and smooth vertical (upper and lower layers) dispersion will clear the concentrations, and the daily average concentration across all regions is expected to be 'Good.'"
Since PM2.5 concentrations will not be high in any region, there should be no major 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)
