About Pollen in Worthing

Worthing experiences peak March-May arboreal pollen from Birch and Oak, originating in urban green spaces including Beach House Park and Highdown Gardens. May-July brings dominant Poaceae (grass) pollen, prevalent across Adur Estuary meadows and Cissbury Ring slopes. Coastal breezes offer some pollen dispersion; however, the South Downs to the north can create inland allergen traps. Late autumn signals increased mould spore counts, particularly from damp, decaying vegetation in areas like Tarring Park.

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