Being part of Surrey, Esher sees an air quality profile that's largely down to traffic and general town-centre activity. The dominant maritime airflow help ventilate the town centre, keeping air quality at moderate levels typical for the region. Commuter traffic feeding onto the A34 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Esher?
Spring and autumn tend to be the calmer, more moderate stretches by comparison. Esher doesn't have one fixed air quality level — it swings between two extremes each year. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A34 closer to ground level. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter.
Are air quality levels in Esher 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.
