About Pollen in Farnborough

Farnborough experiences peak spring tree pollen from March to May; Birch and Oak are dominant, originating from Farnborough Common, Queen Elizabeth Park, and residential tree-lined streets. This transitions to high grass pollen levels throughout June and July, primarily from meadows along the Blackwater Valley Path and extensive local parklands.

Prevailing south-westerly winds often distribute pollen from the wider Surrey/Hampshire green belt; urban heat island effects within Farnborough can trap and concentrate allergens. Autumn brings increased mould spore counts, particularly from September to November, exacerbated by decaying leaf litter and damp conditions around Lakeside Nature Reserve and wooded areas.
