Winter Air Bulletin Summary
During winter, particularly on cold still nights we can expect to see air quality decline in many towns and cities where people are burning solid fuels like peat, coal and wood to heat their homes. Dust concentrations are significantly higher in winter than in the summer. It can be helpful for people with heart or lung conditions including asthma to know when this is happening. Members of the public can check airquality.ie to plan their day and protect their health.
Air Quality Bulletin March 2026 |

The daily limit for PM10 is 50 ug/m3. The limit is deemed breached if more than 35 exceedances occur during the year. The hourly limit for NO2 is 200 ug/m3. The limit is deemed breached if more than 18 exceedances occur during the year. The table below shows the number of exceedances in 2026 to 31/03/26. This data is provisional and subject to future revision following any further data validation. Some of the exceedances may have been caused by short‑term local events, such as roadworks, idling vehicles etc. |

*Note: The decline in air quality on 20 and 21 March 2026 occurred due to stagnant weather conditions, which allowed fine particulate matter from across the continent to accumulate. |
