About Pollen in St Albans

St Albans experiences early spring Birch and Ash pollen, originating from mature street trees and Verulamium Park; Oak pollen follows mid-spring from historic parkland. Summer peaks with high Grass pollen from River Ver meadows, Batchwood Golf Course, and other expansive urban green spaces.

The city’s basin-like topography and urban canyons can intensify pollen trapping. Late season (autumn-winter) features elevated Mould spore counts, driven by damp leaf decomposition in parks, shaded areas, and along the Alban Way, exacerbated by River Ver humidity.

The pollen count in St Albans today is moderate, driven mainly by Mugwort.
