Monterey Bay Aquarium's air quality benefits from its exceptional Pacific Ocean Cannery Row coastal position, with consistent Pacific sea breezes and marine layer providing outstanding maritime ventilation. Vehicle traffic on Cannery Row contributes modest seasonal local sources, while the extraordinary Pacific coastal exposure and the Monterey Bay's open ocean geometry generally maintain the aquarium among California's most reliably ventilated major marine cultural institutions throughout most of the year.

When is air pollution at its worst in Monterey Bay Aquarium?
Air quality at Monterey Bay Aquarium shifts across the year: winter typically brings the cleanest stretch, once occasional rain clears the basin, but summer and early autumn bring the highest ozone levels, and wildfire smoke can spike particulate readings sharply from August through October. Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.
Are air quality levels in Monterey Bay Aquarium 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.
