Pollen Count & Forecast for St Albans, St Albans
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.
