About Pollen in Bracknell

Bracknell’s allergy profile commences March-May with high tree pollen; Birch and Oak, sourced heavily from Swinley Forest and urban green spaces like Lily Hill Park, disseminate widely via prevailing winds. June-August sees peak grass pollen originating from extensive local meadows around The Cut and South Hill Park, intensified by warm, dry conditions.

Built environment microclimates can concentrate airborne allergens, particularly in tree-lined streets. Late autumn to winter, mould spores proliferate from decaying leaf litter in shaded woodlands and damp areas alongside waterways like The Cut, exacerbated by high humidity.

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