Koszalin's air quality benefits from its Baltic Sea coastal position in northwestern Poland, with consistent Baltic westerlies providing reliable maritime ventilation across this Pomeranian city. Vehicle traffic on the S6 expressway and surrounding light manufacturing and agri-food industry contribute local sources, while winter residential coal and wood burning generates seasonal PM2.5 elevation and the Baltic coastal exposure generally maintains more moderate conditions than inland Polish cities.
