About Pollen in Weston-super-Mare

Weston-super-Mare’s spring allergy profile, March-May, is dominated by Birch and Oak pollen originating from urban green spaces like Clarence Park, Grove Park, and surrounding woodlands; May-July introduces prevalent grass pollen from extensive local meadows, Axe Estuary riverbanks, and coastal dune grasses.

Coastal air movement often disperses pollen; however, sheltered urban pockets and parkland topography can concentrate levels. Autumnal dampness and decaying leaf litter in parks and coastal areas elevate mould spore counts, extending allergen exposure.
