Mikkeli's air quality is excellent by European standards, with the Finnish Lake Saimaa system's clean boreal forest airflows and the surrounding lake district providing outstanding natural ventilation. Vehicle traffic on the E63 motorway and wood-burning stoves during the long cold winters are the primary local sources, while the surrounding Finnish lake and forest landscape maintains Mikkeli among Finland's cleanest regional cities throughout most of the year.
