[Suwan News = Environment Reporter] On March 10, 2026, while mostly cloudy or clear weather is expected nationwide, the air quality for ultrafine particulate matter across the country is rated “Poor.”
With overcast skies and high concentrations of fine dust, wearing a medical-grade mask is recommended when going outdoors. According to the general forecast overview, Seoul, northern Gyeonggi, southern Gyeonggi, the Yeongseo region of Gangwon, Daejeon, Sejong, North Chungcheong, North Jeolla, and the Yeongnam region are expected to be rated “Poor,” while other regions are expected to be rated “Moderate.” However, the Yeongdong region of Gangwon is expected to temporarily reach the “Poor” level in the afternoon.
Regarding the causes of these air quality conditions, the agency analyzed: “In most regions, fine dust remaining from the previous day and domestically generated fine dust will accumulate in the morning and at night due to stagnant air and converging air currents, resulting in high concentrations. Although concentrations are expected to decrease in the afternoon due to smooth vertical (upper and lower layer) dispersion, the daily average concentration is forecast to be ‘Poor.’”Detailed PM2.5 air quality ratings for major regions nationwide were observed as follows.
Seoul: Poor, Jeju: Moderate, South Jeolla: Moderate, North Jeolla: Poor, Gwangju: Moderate, South Gyeongsang: Poor, North Gyeongsang: Poor, Ulsan: Poor, Daegu: Poor, Busan: Poor, South Chungcheong: Moderate, North Chungcheong: Poor, Sejong: Poor, Daejeon: Poor, Yeongdong: Moderate, Yeongseo: Poor, Southern Gyeonggi: Poor, Northern Gyeonggi: Poor, Incheon: Moderate
