Napier's air quality benefits from its exceptional Hawke's Bay and Pacific Ocean coastal position in the North Island, with consistent Pacific easterly and Hawke's Bay breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the wine, fruit, and port corridor contribute local sources, while the outstanding Art Deco city coastal exposure and the Hawke's Bay pastoral landscape generally maintain Napier among New Zealand's more moderately ventilated major coastal provincial cities throughout most of the year.

Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Napier based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
