Today, 27th March 2023, marks the start of the pollen season, where Met Éireann provide pollen forecasts on our website and via The Met Éireann app for three days ahead.
The birch tree pollen season has the potential to be quite severe this year and is expected to start in early April, if suitable weather for pollen dispersal occurs. The peak period will last through to late April, with a high to very high risk on dry, sunny days, especially in the east of the country.
The ash pollen season will run at a moderate risk and coincide with the birch pollen season, again mainly in eastern areas. This year the oak pollen season will start from mid-late April and continue into late May.
Grass pollen season will start from around mid-May, with the peak period likely in the middle two weeks of June.
