About Pollen in Dartford

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.

The pollen count in Dartford today is moderate, driven mainly by Perennial Ryegrass.
