About Pollen in Wrexham

Wrexham’s allergy profile begins March-May with high birch pollen, sourced from urban trees and Erddig Estate woodlands; oak pollen follows April-June, pervasive in local parks and surrounding deciduous forests. Summer (May-July) experiences peak grass pollen counts, predominantly from Clywedog Trail meadows and adjacent agricultural land.

Wrexham’s basin-like topography can concentrate airborne pollen, exacerbating exposure. Late-season mould spores (September-November) proliferate from damp leaf litter in areas like Bellevue Park, intensified by the region’s moist climate.

The pollen count in Wrexham today is MED, driven mainly by Grass (mixed).
