Dorking's position in Surrey means air quality is mostly determined by local road traffic and the compact scale of the centre. Onshore breezes usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns. Commuter traffic feeding onto the A40 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Dorking?
Dorking doesn't have one fixed air quality level — it swings between two extremes each year. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A40 traffic emissions linger rather than disperse. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.
Are air quality levels in Dorking 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.
