Commuter traffic feeding onto the A6 adds a further, consistent contribution to local readings. Downpatrick's air quality reflects its position within Newry, Mourne and Down, with local traffic and the town's built-up core as the main contributors. Northwesterly winds off the coast tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Downpatrick?
There's a clear yearly cycle to air quality in Downpatrick if you look closely. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let main road traffic emissions linger rather than disperse. 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. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Downpatrick 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.
