The air quality picture in Falmouth reflects a typical Cornwall town, with traffic emissions and local commercial activity as key contributors. Thanks to the area's changeable Atlantic weather, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards. The nearby M62 corridor contributes steady vehicle emissions that affect roadside readings.

When is air pollution at its worst in Falmouth?
Seasons make a real difference to air quality in Falmouth, more than most people realise. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let M62 traffic emissions linger rather than disperse. 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. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Falmouth 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.
