Patras' air quality reflects its position on the Gulf of Patras at the western entrance to the Gulf of Corinth, with the Achaia lowland plain partially enclosed by the Panachaikon and Erymanthos mountains to the south creating topographic variation. The port's ferry and cargo shipping operations generate elevated NOₓ, while vehicle traffic on the GR-8A and summer ozone from vehicle emissions and intense Mediterranean heat under anticyclonic calm conditions are the primary air quality concerns throughout the year.
