General Comments:
The pollen risk will be occasionally high during good weather but is likely to ease down to moderate levels as more unsettled weather moves in at the start of the next working week. Grass pollen will be the main allergen, with some nettle and lime pollen also airborne.
Tree Comments:
There will be a risk of moderate tree pollen from lime trees in the south-east and Ulster.
Grass Comments:
The grass pollen season is now in peak period of emission so high or very high risk days can be expected when the weather is dry and quite warm.
Weed Comments:
Allergenic weeds are pollinating, including nettle, plantain and dock. These trigger symptoms in around 20% of hay fever sufferers and are mainly a problem in lowland parts.
Spore Comments:
Fungal spores are now at a moderate to high risk during suitable conditions (generally warm and dry or warm and humid). Cladosporium will occur during warm, dry conditions and Didymella, Sporobolomyces and Tilletiopsis during warm, humid nights. Spores affect around 10% of allergic people.
