About Pollen in Bradford

Bradford’s seasonal allergy profile begins late March, peaking April-May with tree pollen; dominant allergens include Birch and Oak, largely sourced from urban green spaces such as Lister Park and Heaton Woods; June to August sees high Grass pollen, prevalent in local meadows, riverbanks like the Bradford Beck, and unmanaged green spaces.

The city’s valley topography often concentrates pollen, intensifying exposure within central areas; autumn, from September to November, brings elevated Mould spore counts, primarily from decaying leaf litter in parks and damp urban environments.
