About Pollen in Liverpool

Liverpool experiences peak Tree Pollen (Birch, Oak, Alder) late March through May, primarily originating from Sefton Park, Calderstones Park, and extensive urban street trees; June to early August features high Grass Pollen, prevalent across River Mersey banks, city parklands, and recreational fields.

The urban built environment often traps pollen, intensifying localised concentrations; late August through November sees elevated Mould Spores, driven by dampness and decomposing leaf litter within Liverpool’s numerous green spaces and shaded urban areas.
