Latest Pollen Information
Outlook for the next two days:
Saturday: Widespread, heavy rain will keep the grass pollen risk low. The tree pollen risk will also be low.
Sunday: The grass pollen risk will remain low but the brighter milder weather will mean there will be some risk from tree pollen.
Grass Pollen Pollen grains from grasses are the most important aeroallergen in Ireland. Grass pollen affects up to about 95% of hay fever sufferers. Some grasses are flowering but grass pollen counts will remain low for this week. Low grass pollen counts may cause symptoms of hay fever in sensitive individuals.
Tree pollen There will be a moderate risk of tree pollen on dry sunny days, with the main risk coming from birch and oak trees. Birch pollen affects around 25% of hay fever sufferers, while oak pollen affects around 20%. The late start to the tree season means birch trees will still be in flower; while the Oak season, which normally runs from late May to June, is just beginning.
Weed pollen The weed pollen risk is currently low. Weed pollen affects about 20% of hay fever sufferers. The main types that can potentially trigger symptoms are Plantain, Dock, Nettle and Mugwort. The main season runs from April to September.
Fungal spores Fungal spores can induce allergic symptoms of the respiratory tract, such as asthma and seasonal allergic rhinitis, in about 10% of those who suffer from seasonal allergies. At the present time, the risk is low. The main season runs from June to October.
