About Pollen in Maidstone

Maidstone’s allergy profile initiates late March with Birch and Oak pollen, originating from Mote Park’s extensive woodlands and Vinters Valley Nature Reserve; high Grass pollen counts dominate May through July, prevalent across Medway riverbanks and surrounding agricultural meadows. The River Medway valley location and surrounding Kentish Downs topography can trap and concentrate airborne pollen; late season extends with mould spores, amplified by damp leaf litter and decaying vegetation in Mote Park and urban green spaces, peaking autumn.
