Kotka's air quality reflects the Gulf of Finland coastal position in eastern Finland, with the Kotka-Hamina port complex's timber, paper, and container operations generating elevated PM2.5 alongside vehicle traffic on the E18 motorway. The Gulf of Finland sea breezes provide coastal ventilation, while the surrounding southeastern Finnish archipelago and the port operations represent the most distinctive local emission sources and the Baltic maritime climate generally maintains moderate conditions throughout most of the year.
