About Pollen in Wandsworth

Wandsworth experiences distinct seasonal allergy peaks: Spring, March-May, features high Birch pollen from Wandsworth Common and Oak pollen prevalent across local street trees and green spaces. Summer, June-July, sees dominant Grass pollen emanating from River Wandle banks and Clapham Common meadows.

Urban architecture, particularly along the Thames corridor, can concentrate airborne particulates, intensifying local exposure. Autumnal dampness in decaying leaf litter, especially within Wandsworth Common’s wooded areas, elevates mould spore counts September-November.
