Florianópolis' air quality benefits from its island position in Santa Catarina Bay, with consistent Atlantic sea breezes from both the ocean-facing and bay-facing shores providing reliable maritime ventilation. Vehicle emissions from the SC-401 and the mainland bridge corridor are the primary local sources, while the Atlantic island geography generally keeps Florianópolis among the better air quality environments for a major Brazilian state capital throughout the year.
