Kateríni's air quality reflects the flat Thessalian plain between Mount Olympus and the Pieria mountains, with vehicle traffic on the E75 motorway and surrounding agricultural and manufacturing industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the Pieria mountains create topographic enclosure and the flat Thessalian coastal plain to the east generally allows reasonable dispersal on easterly Aegean wind days throughout the year.
