About Pollen in Derby

Derby experiences significant spring allergy (March-May) from Birch pollen, prevalent in Darley Park and Markeaton Park, peaking April; Oak follows, mid-April to May, from extensive urban green spaces. Summer (May-July) sees peak Grass pollen from River Derwent flood plains and peripheral meadows, peaking mid-June.

Derby’s Derwent Valley topography can trap airborne allergens, intensifying local concentrations. Autumn (September-November) brings elevated Mould spore levels from decomposing leaf litter in parks and damp urban environments.

The pollen count in Derby today is HIGH, driven mainly by Giant Ragweed.
