About Pollen in Waltham Forest

Waltham Forest experiences peak tree pollen (Birch, Oak, Ash) March-May, originating from Epping Forest’s extensive woodlands and the Lee Valley Regional Park’s varied arboreal zones; grass pollen peaks late May-July, predominantly from Leyton, Hackney, and Walthamstow Marshes’ expansive meadows and River Lea riverbanks.

The Lee Valley’s linear geography can channel and intensify pollen concentrations; urban green spaces (e.g., Lloyd Park, Jubilee Park) create localised hotspots, with dry, windy conditions increasing dispersal; autumn sees elevated outdoor mould spore levels, driven by decomposing leaf litter and damp environments across the borough.

The pollen count in Waltham Forest today is moderate, driven mainly by Mugwort.
