Oakland's Lake Merritt air quality benefits from the 155-acre tidal lagoon's consistent bay breezes providing natural ventilation across this famous Oakland landmark. Vehicle traffic on the surrounding Lakeshore Avenue corridor contributes local sources, while the lake's open water geometry and the Bay Delta maritime influence generally maintain Lake Merritt among Oakland's more moderately ventilated urban lake environments throughout most of the year.

When is air pollution at its worst in Lake Merritt?
This neighborhood in Oakland sees air quality shift through the year. Typically, winter storms periodically reset air quality, keeping the cleanest stretch to the rainy months, while the long dry stretch from midsummer into autumn brings both ozone and wildfire smoke risk. Dry summer conditions with virtually no rain mean pollution and smoke can linger for extended stretches once they arrive.
Are air quality levels in Lake Merritt 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.
