Pollen Count & Forecast for Rotherham, Rotherham

Rotherham’s seasonal allergy profile is pronounced: March-April sees high Birch and Alder pollen from urban trees and River Don floodplain areas; April-May, Oak pollen dominates from local woodlands and parkland, including Clifton Park. Late spring to summer, May-July, grass pollen peaks across extensive local meadows, sports fields, and the banks of the River Don and River Rother.

The town’s valley topography, particularly the River Don corridor, can trap and concentrate airborne pollen. Autumn, September-November, brings elevated mould spore counts, originating from decaying leaf litter and damp vegetation prevalent in parks and shaded residential zones.
