About Pollen in Bournemouth

Bournemouth’s spring allergy season, typically March-May, is dominated by tree pollen: Birch, Alder, and Oak are prevalent, stemming from established urban woodlands including Bournemouth Gardens and Queen’s Park; summer (May-July) sees high grass pollen counts originating from extensive parkland, local verges, and the wider Stour Valley catchment.

Coastal breezes can offer temporary relief; however, sheltered chine valleys like Alum Chine and Boscombe Chine can trap pollen, concentrating local levels; autumn (September-November) sees increased mould spore activity, generated by decaying leaf litter and damp conditions prevalent in wooded areas and the chine systems.

The pollen count in Bournemouth today is HIGH, driven mainly by Giant Ragweed.
