Summary and Weekly Synopsis

Hazel and alder pollen rising to moderate at times. Penicillium and aspergillus spore types will continue to trigger symptoms.

Tree Pollen - Low

Hazel trees are now releasing pollen in generally low amounts. Alder tree pollen is likely to reach a moderate risk this week during mild, dry days.

Grass Pollen - Low

The grass pollen season will start in May.

 

Fungal Spore - Moderate

Penicillium and aspergillus spore types will continue to trigger symptoms in those susceptible, particularly during milder weather. However these types are in decline and most people will probably already have seen a reduction in symptoms. All other spore types are currently at low levels.
