Worst air pollution Finglas, today and tomorrow

On 21 July 2026, overall air quality in Finglas 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 Finglas will be similar to today, with AQI forecast at good at 19.0/100. Pollution peaks around 4:00 PM (O3: 19.0/100).

In Finglas, air quality changes through the year largely because of its residential streets on Dublin's north side. Mild, wet weather keeps the air clean most of the year, though calm winter evenings can let traffic fumes and solid-fuel heating smoke build up locally. A shift in the weather, which happens often here, usually clears any buildup within a day.

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.
