Pollen Count & Forecast for Galway

Galway’s spring allergy season (March-May) is dominated by Birch and Ash pollen; Silver Birch (Betula pendula) common in Merlin Woods; European Ash (Fraxinus excelsior) widespread along River Corrib banks. Oak (Quercus) contributes significantly from Barna Woods. Summer (June-August) sees high Grass (Poaceae) pollen levels, originating from Terryland Forest Park and limestone pastures.

Moist Atlantic air and coastal winds hold pollen, leading to localised high concentrations in the damp air. Autumn and winter see elevated Mould (Cladosporium, Alternaria) spore counts, from decaying leaf litter in Eyre Square and marshes near Salthill.
