Being part of Monmouthshire, Abergavenny sees an air quality profile that's largely down to traffic and general town-centre activity. Prevailing westerlies usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns. The A55 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours.

When is air pollution at its worst in Abergavenny?
For much of spring and autumn, things settle into a fairly unremarkable middle ground. Abergavenny's air quality follows a familiar seasonal pattern most UK towns share. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A55 closer to ground level. 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.
Are air quality levels in Abergavenny 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
