About Pollen in Manchester

Manchester’s allergy profile commences early spring (March-April) with high Birch pollen, originating from urban tree-lined streets and parks like Platt Fields; Oak pollen follows (April-May) from city green spaces including Heaton Park. Summer (May-July) sees dominant Grass pollen, primarily from the Mersey Valley’s expansive meadows and River Irwell’s riverbanks.

The city’s dense urban infrastructure creates a ‘canyon effect,’ trapping and amplifying localised pollen concentrations. Persistent damp autumns (September-November) and winter humidity foster significant Mould spore proliferation from decomposing leaf litter in parks and shaded, unventilated zones.

The pollen count in Manchester today is HIGH, driven mainly by Mugwort.
