Cagliari's air quality reflects its Mediterranean island position in the Gulf of Cagliari, with consistent summer sea breezes from the sea providing reliable ventilation along the Sardinian capital's waterfront. Vehicle traffic on the SS131 Carlo Felice national road and the Cagliari industrial zone's refinery and chemical operations to the northwest generate the primary local emissions, while Saharan dust intrusions from North Africa periodically deliver elevated PM10 and the enclosed Campidano plain's calm anticyclonic conditions can concentrate vehicle and industrial emissions in winter.
