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.

The pollen count in Durham today is MED, driven mainly by Grass (mixed).
