Pollen Count & Forecast for Bromley

Bromley in Bexley experiences significant spring tree pollen: Birch, peaking March/April from extensive urban parkland (e.g., High Elms Country Park) and street trees; Oak and Plane follow April/May, prevalent across suburban green spaces (e.g., Chislehurst Common). Summer brings peak grass pollen from late May through July, originating from abundant local meadows and maintained verges, particularly along River Ravensbourne corridors.

Bromley’s urban-green interface often concentrates airborne allergens; prevailing winds aid dispersal from surrounding Kent countryside. Late summer through autumn sees rising mould spore counts (August-October), exacerbated by damp conditions, leaf litter decomposition in parks, and increased indoor humidity.
