Arendal's air quality benefits from its exceptional Aust-Agder Skagerrak coastal archipelago position, with consistent North Sea and Skagerrak westerlies providing reliable maritime ventilation around this historic timber and sailing city. Vehicle traffic on the E18 and surrounding services and light industrial operations contribute local sources, while the outstanding coastal exposure and the Raet archipelago's open sea geometry generally maintain Arendal among Norway's more pleasantly ventilated southern coastal cities throughout most of the year.
