Abomey-Calavi's air quality reflects the flat Benin Atlantic coastal position adjacent to Cotonou on Lake Nokoué, with vehicle density, motorcycle traffic, and the extraordinary Dahomey heritage tourism and educational corridor contributing local sources. Consistent Gulf of Guinea maritime breezes provide coastal ventilation, while dry season Harmattan dust elevates PM10 and Abomey-Calavi generally maintains moderate Beninese Atlantic coastal metropolitan readings throughout most of the year.
