About Pollen in Weymouth

Spring presents peak Birch pollen (late March-April) from Weymouth’s urban trees and Nothe Gardens; Oak pollen follows (April-May) from parkland and Radipole Lake surrounds. Summer sees high Grass pollen (May-July) from bordering meadows and River Wey catchment.

Coastal air currents influence pollen dispersal, yet Weymouth’s sheltered urban pockets can concentrate allergens; late autumn-winter exhibits elevated Mould spores, exacerbated by damp conditions and decaying foliage in areas like Sandsfoot Gardens and Radipole Lake.
