About Pollen in Woking

Woking’s allergy profile begins March-May with high Birch and Oak pollen counts, originating from mature trees within Woking Park, Horsell Common, and along the Basingstoke Canal; May-July sees dominant Grass pollen from surrounding meadows, waterway verges, and residential lawns.

Urban heat island effects and building configurations can locally amplify pollen concentrations; adjacent heathland and woodland, like those near Chobham Road, significantly contribute to early-season tree pollen burdens. Late-season Mould spores are prevalent September-November, intensified by damp, decaying leaf litter in parks and shaded suburban environments.
