Přerov's air quality reflects its position on the Bečva river plain in Moravia, with chemical-industry emissions and vehicle traffic across the plain contributing the main local sources through the year. Weather patterns typical of Olomouc Region shape how quickly pollutants clear, with conditions generally improving whenever winds pick up or rain moves through, while calmer, high-pressure spells tend to let local emissions accumulate for longer than elsewhere in the region.
