Pollen Count & Forecast for Huddersfield, Calderdale

Huddersfield’s spring allergy profile is dominated by Birch and Oak pollen, peaking late March to early June from mature trees in Beaumont Park, Tolson Museum grounds, and surrounding urban woodlands; May to July sees high Grass pollen from River Colne/Holme valley meadows, playing fields, and suburban verges. Calderdale’s valley topography often traps airborne pollen within the urban bowl, exacerbating local concentrations; late summer into autumn, particularly September-November, experiences elevated outdoor Mould spore counts, driven by dampness, leaf litter decomposition in parks and gardens.
