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.

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