Folkestone sits within Kent, and its air quality profile is driven mainly by road traffic and the density of the centre. Commuter traffic feeding onto the A1 adds a further, consistent contribution to local readings. Thanks to prevailing westerlies, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards.

When is air pollution at its worst in Folkestone?
Folkestone doesn't have one fixed air quality level — it swings between two extremes each year. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily. Through the colder months, readings near the A1 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Spring and autumn tend to be the calmer, more moderate stretches by comparison.
Are air quality levels in Folkestone 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.
