General Comments:

Weed and grass pollen will be mainly low for a while, possibly reaching moderate in Leinster during better weather on Monday. Fungal spores will remain at a high risk, particularly for the damp weather spore types.

Tree Comments:

Tree pollen will be low everywhere.

Grass Comments:

Grass pollen is now in terminal decline and the risk will be low.

Weed Comments:

Weed pollen will be moderate for a while, with nettle, pellitory-of-the-wall and a few other types in flower (mainly affecting the eastern fringes of the country).

Spore Comments:

Fungal spores will be high, only reducing to low during heavy rainfall. Leptosphaeria, Didymella, Tilletiopsis and Sporobolomyces will rise to high during warm, humid conditions, typically at night. Cladosporium, Alternaria and Epicoccum will be airborne during warm, dry weather.
