About Pollen in Blackburn

Spring brings peak Birch, Alder, and Oak pollen (March-May) from surrounding woodlands including Tyrebagger Forest and mature trees within Blackburn’s green spaces; intense Grass pollen follows (June-July) from bordering agricultural fields and River Don riparian zones.

Westerly winds frequently transport pollen from extensive farmlands; localised still air around Blackburn’s buildings can concentrate particulate levels. Autumn’s damp conditions foster high Mould spore counts (Sept-Oct) from decomposing leaf litter in local woodlands and parklands, completing the annual allergy profile.

The pollen count in Blackburn today is high, driven mainly by Stinging Nettle.
