Sandefjord's air quality benefits from its exceptional Oslofjord coastal position, with consistent fjord and North Sea westerlies providing reliable maritime ventilation across this historic Norwegian whaling and shipping city. Vehicle traffic on the E18 and Sandefjord Airport's aviation operations contribute local sources, while the fjord's open geometry and consistent maritime winds generally maintain Sandefjord among the Oslofjord region's cleaner coastal urban environments throughout most of the year.
