Sheboygan's air quality benefits from Lake Michigan's powerful westerly lake winds providing consistent clean maritime ventilation along the Wisconsin shoreline. Vehicle emissions from I-43 and the surrounding manufacturing and food processing industry contribute local sources, while summer regional ozone from Great Lakes industrial sources and the surrounding agricultural landscape are the primary warm-season concerns and lake-effect weather provides effective periodic atmospheric washing throughout the year.
