Zalaegerszeg's air quality reflects the Zala river valley in the western Hungarian Transdanubia, with vehicle traffic on the M76 expressway and the surrounding automotive and manufacturing industry contributing local sources. The Zala hills create topographic variation, while winter residential heating and temperature inversions in the Zala basin contribute seasonal PM2.5 elevation and the western Hungary position generally provides somewhat cleaner Atlantic-influenced airflows than eastern Hungary's more continental winter inversion episodes throughout the year.
