About Pollen in Warrington

Warrington’s spring pollen season, March-May, is dominated by Birch, Oak, and Ash; peak concentrations emanate from urban woodlands like Sankey Valley Park and Walton Hall Gardens. Summer, May-July, sees high grass pollen from abundant riverine meadows along the Mersey and open parklands.

The city’s basin topography and dense urbanisation can trap airborne particulates, elevating localised pollen counts; late autumn to winter brings mould spores, exacerbated by damp leaf litter decomposition in wooded areas and wetlands such as Risley Moss.

The pollen count in Warrington today is moderate, driven mainly by Perennial Ryegrass.
