Wexford's air quality benefits from its southeastern Irish Sea coastal position, with maritime breezes providing reliable ventilation. Vehicle traffic on the N11 and N25 is the primary local source.

When is air pollution at its worst in Wexford?
Throughout the year, air quality in Wexford rises and falls with the seasons, shaped by its harbourside setting on the River Slaney estuary. The open Atlantic keeps the air fresh nearly year-round, apart from rare still winter nights when turf or coal smoke can settle over the town. A shift in the wind off the sea usually clears any buildup within a day.
Are air quality levels in Wexford 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.
