Galway's air quality benefits from Ireland's exceptional Atlantic Ocean exposure on the Wild Atlantic Way, with consistent powerful westerly winds from the Atlantic providing some of Europe's most reliable natural ventilation. Vehicle traffic on the N6 and surrounding pharmaceutical and medical device manufacturing industry contribute local sources, while the Atlantic coastal climate's stormy weather and high rainfall provide outstanding natural atmospheric washing throughout most of the year.
