San Diego's Ocean Beach air quality benefits from its direct Pacific Ocean coastal position, with consistent onshore sea breezes providing reliable and powerful maritime ventilation along the OB pier and beach neighbourhood. Vehicle traffic on Voltaire Street and the surrounding residential and surf culture character contribute modest local sources, while the outstanding Pacific coastal exposure and the open ocean geometry ensure reliable ventilation and generally maintain Ocean Beach among San Diego's cleanest coastal neighbourhoods throughout most of the year.

Are air quality levels in Ocean Beach 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.
