Being part of Surrey, Reigate sees an air quality profile that's largely down to traffic and general town-centre activity. The A14 sees the heaviest traffic, and that shows up clearly in local roadside monitoring. Light prevailing breezes usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Reigate?
Here's the thing about Reigate: air quality has a clear seasonal rhythm. In deep winter, a lack of wind lets A14 traffic fumes and woodsmoke settle instead of blowing through. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Reigate 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.
