Air quality in Totnes is shaped by its location in Devon, where vehicle traffic and everyday urban activity dominate local sources. Northwesterly winds off the coast help ventilate the town centre, keeping air quality at moderate levels typical for the region. The A14 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours.

When is air pollution at its worst in Totnes?
You can roughly predict Totnes's air quality just by knowing the time of 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. Winter mornings can be the trickiest, with cold, still conditions trapping A14 traffic fumes and smoke from home fires close to the ground.
Are air quality levels in Totnes 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.
