Saronno owes much of its air quality variation to vehicle traffic in the dense Milan metropolitan belt, compounded by its position on the Lombard plain between Milan and Varese. The surrounding Lombardia terrain can either help disperse or trap these emissions depending on the weather, with active, breezy conditions generally bringing the clearest air.
