Air quality for ultrafine particulate matter nationwide is forecast to be "moderate" on August 2, 2026.
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 regions, concentrations will rise in the morning and at night as fine dust remaining from the previous day and domestically generated fine dust accumulate due to stagnant air; however, concentrations will 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, South Gyeongsang, North Gyeongsang, Ulsan, Daegu, Busan, North Chungcheong, Sejong, Daejeon, Yeongseo, Southern Gyeonggi, Northern Gyeonggi, Incheon (13 regions)
Good — Jeju, South Jeolla, North Jeolla, Gwangju, South Chungcheong, Yeongdong (6 regions)
