Being part of Angus, Forfar sees an air quality profile that's largely down to traffic and general town-centre activity. Commuter traffic feeding onto the M74 adds a further, consistent contribution to local readings. Onshore breezes tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Forfar?
Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching. There's a clear yearly cycle to air quality in Forfar if you look closely. Winter mornings can be the trickiest, with cold, still conditions trapping M74 traffic fumes and smoke from home fires close to the ground. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter.
Are air quality levels in Forfar 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.
