Oyster Bay's air quality benefits from its Long Island Sound coastal position, with consistent northerly Long Island Sound breezes providing maritime ventilation along this suburban Nassau County shoreline. Vehicle emissions from the Northern State Parkway and the Long Island Rail Road commuter corridor are the primary local sources, while prevailing westerlies carry the broader New York City metropolitan area pollution plume eastward across Long Island, elevating background ozone above what the coastal position would otherwise suggest.

When is air pollution at its worst in Oyster Bay?
Oyster Bay's air quality follows a clear seasonal pattern: frequent frontal systems in spring and fall usually keep the air cleanest then, but summer heat and regional haze drifting up from the Midwest and South drive ozone spikes. Winter cold fronts tend to clear the air quickly, so extended pollution episodes are relatively uncommon.
Are air quality levels in Oyster Bay 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.
