About Pollen in York

York’s allergy profile commences March-April with Birch and Elm pollen, originating from urban green spaces like Rowntree Park and Museum Gardens; Oak pollen follows into May from city parklands. Grass pollen dominates May-July, primarily from Ouse/Foss riverbanks and open areas such as Knavesmire, exacerbated by dry, windy conditions.

York’s urban landscape, particularly its river valleys and built environment, can concentrate airborne allergens; prevailing south-westerly winds commonly disseminate pollen throughout the city. Late-season allergies (September-November) predominantly involve mould spores, stemming from damp leaf litter and decaying organic matter in parklands like St Nicholas Fields, intensified by autumn rainfall and high humidity.

The pollen count in York today is moderate, driven mainly by Mugwort.
