Bilbao's air quality has improved dramatically since the industrial era but remains influenced by the Nervión valley's enclosed topography, with the surrounding Cantabrian mountains limiting dispersal on calm days. Atlantic westerlies from the Bay of Biscay provide the primary natural ventilation, while vehicle traffic and remaining industrial activity in the lower valley are the primary local emission sources.
