Overall, Nyköping maintains air quality that compares well with Swedish and wider European norms. Logistics near Skavsta airport represents the area's most notable emission source, alongside routine road traffic through the centre. Because of its position near the Nyköpingsån river mouth, the area rarely sees pollutants linger for more than a day or two. Taken together, these factors leave Nyköping with air quality conditions typical of similarly sized Swedish communities.

When is air pollution at its worst in Nyköping?
Does air quality in Nyköping vary by season? Air quality dips are most common in winter, when heating season overlaps with the calm, cold weather that traps local emissions. By spring, more frequent fronts and wind usually disperse pollutants faster, even as tree pollen becomes the bigger seasonal concern. The summer months tend to be the least problematic, aside from the occasional heatwave that can nudge ozone levels upward. Autumn sees a gradual decline from summer's good conditions, as cooler weather brings back wood-smoke and less consistent wind. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.
Are air quality levels in Nyköping 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.
