About Pollen in Hereford

Hereford’s spring allergen profile (March-May) features dominant Birch and Oak pollen from city parks like Castle Green and surrounding deciduous woodlands; Alder contributes earlier (February-March) along the River Wye banks; summer (May-July) sees high grass pollen levels, particularly from Bishops Meadow, King George V Playing Fields, and surrounding agricultural areas. The Wye Valley’s topographical bowl often traps pollen, increasing local atmospheric concentrations; late-season (August-November) mould spores, exacerbated by Herefordshire’s damp conditions, originate from decaying vegetation and leaf litter prevalent in floodplains and urban green spaces.

The pollen count in Hereford today is moderate, driven mainly by Mugwort.
