Pollen Count & Forecast for Oldham, Oldham

Oldham’s allergy season commences early spring (March-May) with Birch and Oak pollen; prevalent across Alexandra Park, Tandle Hill Country Park, and local woodland. Summer (May-July) brings high grass pollen counts from urban verges, Medlock Valley, and Saddleworth Moor fringes.

Oldham’s elevated topography within the Pennine foothills can trap pollen, locally intensifying concentrations. Late autumn-winter, mould spores proliferate; generated by damp leaf litter decomposition in parks and shaded, moist environments.
