About Pollen in Sheffield

Sheffield’s allergy season commences early spring (February-April) with tree pollen: dominant Birch and Oak, largely sourced from the city’s extensive urban parks like Endcliffe Park and surrounding woodlands such as Ecclesall Woods; late spring through mid-summer (May-July) sees peak grass pollen levels, prevalent across the city’s abundant parkland meadows and river valley floodplains.

Sheffield’s unique valley topography and surrounding hills can concentrate and trap airborne pollen, intensifying local symptoms; autumn (September-November) brings elevated mould spore counts, particularly from damp leaf decomposition in parks and wooded areas.
