Pollen Count & Forecast for Barnsley

Barnsley’s spring allergen profile peaks March-April with Alder and Hazel; April-May, Birch and Oak pollen from extensive woodlands at Locke Park and Wentworth Castle Gardens dominates, circulating throughout the urban area. Summer (May-July) transitions to significant grass pollen from the River Dearne floodplains and surrounding agricultural meadows.

The town’s valley topography, influenced by the Pennine foothills, can trap and concentrate airborne pollen loads. Autumn sees increased mould spores, particularly from damp conditions in local parks and near Worsbrough Reservoir, associated with decomposing organic matter.
