Surabaya's air quality reflects Java's second city on the Madura Strait coast, with vehicle traffic on the Jalan Tol Surabaya-Gresik and the surrounding Gresik industrial complex, Petrokimia fertiliser plant, and manufacturing corridor generating elevated industrial PM2.5 and NOₓ. The Java Sea monsoon breezes provide seasonal ventilation, while the surrounding Gresik industrial complex's scale and the extraordinary two-stroke vehicle density maintain Surabaya at consistently elevated East Java metropolitan readings throughout most of the year.
