About Pollen in Basingstoke

Basingstoke’s spring allergy season (March-May) is dominated by Birch and Oak pollen, sourced from urban green spaces like Eastrop Park, War Memorial Park, and Crabtree Plantation; summer (June-July) sees peak grass pollen from extensive parklands and surrounding agricultural verges, including areas adjacent to the River Loddon. The city’s built environment, particularly within central districts, can create localised ‘pollen trap’ zones, intensifying exposure; late autumn and winter (October-February) present elevated mould spore levels from decaying organic matter in damp, shaded urban areas and drainage channels.

The pollen count in Basingstoke today is HIGH, driven mainly by Mugwort.
