About Pollen in St Helens

St Helens’ seasonal allergy profile sees early spring (March-April) dominated by tree pollens: Hazel and Alder active near Bembridge Harbour; Birch and Oak prevalent across St Helens Green and village gardens. Late spring (May-June) adds Pine pollen. Summer (June-August) brings high Grass pollen from surrounding agricultural fields and coastal grasslands, notably St Helens Duver.

Coastal winds across St Helens Bay can disperse pollen; however, local sheltered areas and the Bembridge Harbour estuary environment may concentrate it. Autumn (September-November) brings elevated mould spore levels from decaying vegetation around the harbour fringes and damp leaf litter within village residential areas.
