Worst air pollution Raheny - Dublin, today and tomorrow

On 21 July 2026, overall air quality in Raheny is good. AQI is the main air quality indicator at 19.3/100. Pollution peaks around 5:00 PM (O3: 19.3/100).

On 22 July 2026, air quality conditions in Raheny will be similar to today, with AQI forecast at good at 19.0/100. Pollution peaks around 4:00 PM (O3: 19.0/100).

Throughout the year, air quality in Raheny rises and falls with the seasons, shaped by its residential streets near Dublin Bay's northern shore. Damp, breezy Atlantic weather dominates most of the year, with only calm winter nights occasionally allowing local traffic and heating smoke to linger. Being away from the busiest city-centre streets usually means slightly calmer conditions than downtown.

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.

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.
