About Pollen in Durham

Durham’s spring allergy profile is dominated by tree pollens: Birch and Oak peak late-April through May, originating from the extensive tree populations within the University Botanic Garden, Cathedral grounds, and wider city green spaces; this transitions to high grass pollen levels throughout June and July, primarily from the River Wear meadows and Flass Vale.

Durham’s characteristic river valley and surrounding hills often create a sheltered environment, trapping airborne pollen and intensifying local concentrations; late-season allergen exposure then shifts to mould spores, prevalent from October onwards due to decaying leaf litter and damp conditions common in local parks and shaded areas.
