Pollen Count & Forecast for Dartford, Bexley

Dartford’s allergy season begins spring (March-May) with high Birch and Oak pollen, primarily from Central Park, Darenth Country Park, and wider urban woodland fringes; summer (June-July) sees dominant Grass pollen from Darent Valley riverbanks and local meadows.

Local topography, particularly the Darent Valley, influences pollen dispersion and trapping; late autumn brings increased Mould spore exposure, linked to decomposing leaf litter in green spaces and damp conditions.
