Borås' air quality is generally good, with consistent North Sea and Kattegat westerlies providing reliable maritime ventilation across this southwestern Swedish textile and logistics city. Vehicle traffic on the E20 motorway and surrounding manufacturing contribute the primary local sources, while wildfire smoke from drought conditions increasingly affects summer readings across the surrounding Sjuhärads forested landscape.

When is air pollution at its worst in Borås?
How does air quality change throughout the year in Borås? The darkest winter months tend to bring the year's weakest readings, since calm, cold air allows pollutants from heating and traffic to accumulate rather than disperse. Air quality tends to recover through spring as milder, windier conditions replace the still winter air masses. The summer months tend to be the least problematic, aside from the occasional heatwave that can nudge ozone levels upward. Autumn generally marks the year's decline back toward winter conditions, driven mainly by the return of wood-burning and stiller air. Given the region's milder winters, the contrast between the seasons here tends to be gentler than in northern Sweden.
Are air quality levels in Borås 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.
