Perth's position in Perth and Kinross means air quality is mostly determined by local road traffic and the compact scale of the centre. Traffic on the A82 is the most significant local emissions source, especially at peak times. Residential heating and light industry add a modest seasonal contribution, though moist Atlantic fronts keep overall levels moderate.

When is air pollution at its worst in Perth?
Here's the thing about Perth: air quality has a clear seasonal rhythm. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Through the colder months, readings near the A82 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Perth 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.
