Stockholm's Södermalm records moderate Stockholm air quality in this characterful southern island district, with Götgatan and Hornsgatan traffic contributing to local emissions at typical inner Stockholm levels. The Riddarfjärden waterfront to the north and the open Hammarbykanalen to the south provide limited ventilation corridors, while the island topography creates some variation between hilltop and valley street levels.

When is air pollution at its worst in Södermalm?
How do the seasons affect air quality in Södermalm? Winter is generally when local emissions build up most, since cold, stagnant air limits how quickly wood-smoke and exhaust clear. From spring onward, increasing wind and precipitation generally break up the stagnant conditions that caused winter dips. Most of the year's best readings occur in summer, with only rare hot, calm days causing a temporary rise in ground-level ozone. The transition into autumn typically brings a slow return of the wood-smoke and calm-air conditions that peak in winter. This pattern reflects a fairly classic central Swedish climate, with clear seasonal transitions.
Are air quality levels in Södermalm 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.
