About Pollen in Stockport

Stockport’s allergy season commences March-May with high tree pollen (Birch, Oak, Hazel) from mature woodlands in Woodbank Park, Vernon Park, and the Mersey Valley, intensified by dry, windy spring conditions. Grass pollen peaks May-July, widely dispersed from local meadows, sports fields, and riverbanks along the Mersey and Goyt.

The borough’s valley topography can trap pollen in sheltered urban green spaces, escalating local concentrations. Late-season allergies are predominantly mould spores, September-November, driven by damp, decomposing leaf litter in parks and wooded areas following autumn rainfall.
