About Pollen in Reading

Reading’s spring allergy season begins late March: Birch and Oak pollen dominate from extensive urban green spaces like Palmer Park, Prospect Park, and the University of Reading campus, peaking April-May; June-July sees high Grass pollen levels originating from River Thames and Kennet floodplain meadows and local parklands.

Reading’s Thames Valley topography can trap pollen, amplifying local concentrations; late summer into autumn brings elevated Mould spore levels, particularly from decomposing foliage in damp, shaded locales and riverbank vegetation.
