About Pollen in Solihull

Spring sees high Birch and Oak pollen counts, originating from mature trees within Brueton Park, Malvern Park, and Solihull’s extensive tree-lined residential avenues; summer transitions to prevalent Grass pollen, particularly from Olton Mere’s surrounding meadows and River Cole’s floodplains.

Solihull’s parkland-rich topography and built environment can trap pollen, concentrating local allergen exposure; late autumn and winter feature elevated Mould spore levels, primarily from damp leaf decomposition in local woodlands and shaded urban zones.
