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.
