On August 26, 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.” However, Ulsan is expected to temporarily reach “Poor” during the daytime.
Regarding the cause, the agency analyzed, “In most southern regions, atmospheric convergence will cause fine dust carried over from the previous day and domestically generated fine dust to accumulate, 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 — South Jeolla, South Gyeongsang, North Gyeongsang, Ulsan, Daegu, Busan (6 regions)
Good — Seoul, Jeju, North Jeolla, Gwangju, South Chungcheong, North Chungcheong, Sejong, Daejeon, Yeongdong, Yeongseo, Southern Gyeonggi, Northern Gyeonggi, Incheon (13 regions)
