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.

The pollen count in Weymouth today is low, driven mainly by Pigweed.
