Coleraine's air quality reflects its position within Causeway Coast and Glens, with local traffic and the town's built-up core as the main contributors. Residential heating and light industry add a modest seasonal contribution, though moist Atlantic fronts keep overall levels moderate. Traffic on the M2 is the most significant local emissions source, especially at peak times.

When is air pollution at its worst in Coleraine?
If you're tracking air quality in Coleraine, expect it to move around quite a bit through the 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. The coldest months usually bring the worst readings, as heating and temperature inversions keep main road emissions from dispersing normally.
Are air quality levels in Coleraine 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.
