Pollen Count & Forecast for Cork

Cork’s spring allergy season (March-May) is dominated by Birch and Ash pollen; Birch (Betula) prolific in Fitzgerald Park and University College Cork grounds; Ash (Fraxinus excelsior) widespread along the River Lee banks. Oak (Quercus) contributes significantly from Tramore Valley Park. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from the Curragheen River meadows and Bishopstown.

The city’s valley topography traps pollen in the urban centre; damp Atlantic winds increase humidity levels. Autumn and winter see high Mould (Alternaria, Cladosporium) spore counts, from decomposing leaf litter in Glen River Park and damp environments along the river quays.
