About Pollen in Bexley

Bexley’s allergy profile initiates late winter; Alder and Hazel pollen peak from woodland margins like Joydens Wood; mid-spring sees Birch and Oak pollen proliferate across Danson Park and Hall Place Gardens; Plane tree pollen follows, abundant along urban streets. Summer brings high Grass pollen counts, particularly from open areas such as Footscray Meadows and River Cray floodplains, exacerbated by warm, dry, windy conditions.

The River Cray valley’s topography can concentrate airborne pollen; autumn transitions to elevated Mould spore counts, driven by damp leaf litter decomposition in parks and shaded residential zones.
