Strömstad's air quality is generally good by Swedish and European standards, with only occasional local peaks in pollutant levels. Fishing and cross-border retail, together with ordinary road traffic, accounts for most of the area's local emissions. Because of its position near the rocky Bohuslän archipelago, the area rarely sees pollutants linger for more than a day or two. In practice, Strömstad rarely sees air quality readings that stand out from the Swedish norm.

When is air pollution at its worst in Strömstad?
How does air quality change throughout the year in Strömstad? The coldest months bring the year's more frequent air quality dips, mostly linked to wood-burning stoves and traffic on still winter days. The changeable spring weather generally keeps pollutant levels lower than in winter, even as pollen becomes more relevant. Warm-season conditions are generally the most favourable of the year, with wood-burning emissions largely absent. By October and November, cooling air and calmer evenings start to mirror the patterns that intensify further in winter. This pattern is fairly typical for central Sweden, where all four seasons are clearly distinct.
Are air quality levels in Strömstad 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
