Sankt Pölten's air quality reflects the Traisen river valley in the Lower Austrian Alpine foreland, with vehicle traffic on the A1 motorway and the surrounding manufacturing and government administration contributing local sources in Austria's federal state capital. The Alpine foothills to the south and the Viennese Woods create topographic variation, while the Alpine Föhn wind periodically delivers clean mountain air and the Danube basin's regional winter anticyclone can extend westward to affect the Traisen valley throughout the year.
