Galway's air quality benefits from Ireland's exceptional Atlantic Ocean exposure on the Wild Atlantic Way, with consistent powerful westerly winds from the Atlantic providing some of Europe's most reliable natural ventilation. Vehicle traffic on the N6 and surrounding pharmaceutical and medical device manufacturing industry contribute local sources, while the Atlantic coastal climate's stormy weather and high rainfall provide outstanding natural atmospheric washing throughout most of the year.

When is air pollution at its worst in Galway?
Galway sees clear seasonal swings in air quality, driven in part by its position where the River Corrib meets Galway Bay. Damp, breezy conditions dominate most of the year, though calm, cold winter evenings occasionally let traffic fumes and coal or turf smoke linger over the city. Atlantic weather systems pass through frequently enough that pollution rarely lingers for long.
Are air quality levels in Galway 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.
