About Pollen in Leeds

Leeds’ spring allergy profile, peaking April-May, is dominated by Birch and Oak pollen, primarily sourced from extensive urban woodlands including Roundhay Park and Golden Acre Park; May-July sees high Grass pollen levels, originating from River Aire floodplains and city green spaces.

The city’s topography, including the Aire Valley, can trap and concentrate pollen locally; Mould spores emerge late-season, August-November, fuelled by damp organic matter decomposition across Leeds’ parks and shaded urban zones.

The pollen count in Leeds today is moderate, driven mainly by Western Ragweed.
