The dominant influence on Lecco's air quality is vehicle traffic funnelled along the narrow lake-and-mountain corridor, layered onto a setting on the eastern shore of Lake Como beneath the Grigne peaks within Lombardia. Ventilation here depends heavily on wind and rainfall, with the calmest, most stagnant periods generally producing the least favourable readings.
