Pollen Count & Forecast for Lewisham

Lewisham’s allergy season commences early spring (March-May) with dominant Birch and Oak pollen, originating from mature trees in Blackheath, Greenwich Park, and along the Ravensbourne River corridor; summer (May-July) peaks with Grass pollen, prevalent in Ladywell Fields, Hilly Fields, and other urban green spaces. Lewisham’s urban topography and varied parklands can localise pollen concentrations.
