Being part of Buckinghamshire, Gerrards Cross sees an air quality profile that's largely down to traffic and general town-centre activity. Northwesterly winds off the coast offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns. Commuter traffic feeding onto the M62 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Gerrards Cross?

Gerrards Cross doesn't have one fixed air quality level — it swings between two extremes each year. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. Winter mornings can be the trickiest, with cold, still conditions trapping M62 traffic fumes and smoke from home fires close to the ground. The shoulder seasons generally bring the mildest readings of the year.

Are air quality levels in Gerrards Cross 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.
