About Pollen in Basildon

Basildon’s allergy profile begins late March-May with high Birch and Oak pollen, primarily from local woodlands (e.g., Gloucester Park) and urban trees; Plane tree pollen significantly contributes in town centre avenues; June-August sees peak Grass pollen, particularly from extensive meadows surrounding Basildon and along the River Crouch and its tributaries.

The city’s varied green spaces and sheltered areas can concentrate airborne allergens, especially during warm, still conditions; late autumn-winter (September-November) elevated Mould spores predominate, stemming from damp leaf litter decomposition in shaded parks and surrounding marshlands.
