Stockholm's air quality is excellent by European standards, with clean Baltic and Atlantic airflows dominating conditions and the archipelago city's water channels providing natural ventilation across the urban fabric. Vehicle traffic and winter wood burning contribute the primary local emissions, while Stockholm's progressive transport policies have steadily reduced the city's traffic-related pollution burden over recent decades.

When is air pollution at its worst in Stockholm?
What is the yearly air quality pattern like in Stockholm? Midwinter is generally the least favourable period, as still air and cold temperatures allow local pollutants to build up rather than clear. Spring's changeable weather tends to prevent the kind of stagnant air that causes winter pollution episodes. The year's most consistently good air usually falls in summer, when heating season has ended and ventilation improves. Conditions gradually shift through autumn, with cooling temperatures reviving wood-burning and calmer nights allowing brief local build-ups. This pattern is fairly typical for central Sweden, where all four seasons are clearly distinct.
Are air quality levels in Stockholm 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.
