About Pollen in Bedford

Bedford experiences peak spring tree pollen, primarily Birch and Oak, from late March through May, originating prominently from The Embankment’s mature trees and Priory Country Park’s woodlands. Summer transitions to high Grass pollen counts, typically June-July, prevalent across the River Great Ouse floodplains and local park meadows.

The Great Ouse valley topography and urban-edge microclimates can concentrate pollen levels, intensifying exposure; late autumn, October-November, sees elevated Mould spore activity, largely from damp leaf litter decomposition in wooded areas and riverine environments.
