About Pollen in Leicester

Leicester city, Blaby, experiences peak spring (March-May) tree pollen; Birch and Oak are prolific, sourced from Victoria Park and Abbey Park’s mature canopy. Summer (June-August) sees high grass pollen, originating from River Soar floodplains and peripheral meadows.

The city’s urban topography often traps pollen, exacerbating localized concentrations. Autumn-winter brings elevated mould spore counts, fuelled by decomposing leaf litter and damp conditions common to parks and green spaces.

The pollen count in Leicester today is V.HI, driven mainly by Sagebrush.
