Mombasa's air quality benefits from its exceptional Kenyan Indian Ocean coastal position on Mombasa Island, with consistent Indian Ocean southwest and northeast monsoon breezes providing reliable maritime ventilation. Vehicle traffic on surrounding roads and the port — East Africa's largest — vehicle density, and industrial corridor contribute elevated PM2.5, while the outstanding Indian Ocean coastal exposure generally maintains Mombasa among East Africa's more moderately ventilated major Indian Ocean coastal port environments throughout most of the year.

Are air quality levels in Mombasa 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.
