Pollen Count & Forecast for Rochdale

Rochdale’s spring allergy profile peaks with tree pollens: Birch and Oak dominate March-May, originating from mature trees within Broadfield Park, Healey Dell Nature Reserve, and general urban green spaces; Grass pollen follows, intense May-July, widely dispersed from meadows, sports fields, and River Roch banks.

Topography influences local pollen concentrations; Rochdale’s valley location within the Pennine foothills can trap airborne allergens, exacerbating symptoms. Autumn sees increased mould spore activity (September-November) driven by damp conditions, leaf litter decomposition in wooded areas, and general urban humidity.
