Worst air pollution Bray, today and tomorrow

On 9 August 2026, overall air quality in Bray is fair. AQI is the main air quality indicator at 33.3/100. Pollution peaks around 4:00 PM (O3: 33.3/100).

On 10 August 2026, air quality conditions in Bray will be similar to today, with AQI forecast at fair at 23.8/100. Pollution peaks around 4:00 PM (O3: 23.8/100).

In Glendalough, air quality changes through the year largely because of its monastic ruins set among the lakes of the Wicklow Mountains. Air quality here is generally excellent year-round, kept clean by near-constant Atlantic wind and rain, with summer visitor traffic the only modest local source. Outside of peak tourist season, conditions here are about as clean as anywhere in Ireland.

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.
