Słupsk's air quality benefits from its Baltic Sea coastal proximity in Pomerania, with consistent Baltic westerlies providing reliable maritime ventilation across this northern Polish city. Vehicle traffic on the S6 expressway and surrounding 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 throughout the year.
