Krems an der Donau's air quality reflects the Danube valley at the Wachau wine region entrance in Lower Austria, with vehicle traffic on the A33 motorway and surrounding wine, tourism, and light manufacturing operations contributing local sources. The Danube valley provides ventilation on westerly winds, while the surrounding Waldviertel hills and the Bohemian Massif create topographic variation and the Alpine Föhn wind periodically delivers clean mountain air throughout the year.
