About Pollen in Worcester

Worcester’s spring allergy profile is dominated by Birch and Oak pollen, prevalent from late March to May across urban green spaces including Gheluvelt Park and surrounding Malvern Hills woodlands; May to July brings peak Grass pollen, originating from extensive riverside meadows bordering the River Severn and River Teme.

Local topography, particularly the Malvern Hills, influences pollen dispersal and trapping; autumn through winter sees elevated mould spore counts, driven by decaying leaf litter in parks and persistent damp along the River Severn’s banks.

The pollen count in Worcester today is high, driven mainly by Mugwort.
