Pollen Count & Forecast for Folkestone

Folkestone’s primary allergy season initiates late March with Birch pollen, prevalent through April from mature trees along The Leas and Radnor Park; April to May introduces significant Oak pollen, originating from scattered deciduous trees within urban green spaces. Late May through July marks peak Grass pollen levels, primarily from extensive coastal grasslands, managed verges, and surrounding agricultural areas.

The town’s coastal topography, featuring cliffs and sheltered valleys, can locally trap pollen, intensifying exposure; late autumn through winter sees elevated Mould spore counts, particularly with damp conditions and decaying leaf litter in parks and near the Pent Stream, contributing to perennial symptoms.
