About Pollen in Richmond upon Thames

Richmond upon Thames experiences peak spring tree pollen (Birch, Oak) March-May, originating from extensive woodlands within Richmond Park, Bushy Park, and Kew Gardens; ubiquitous grass pollen dominates June-August, prevalent across Thames riverside meadows and urban green spaces.

Richmond’s Thames Valley location and prevailing winds can concentrate pollen, exacerbating local exposure; late autumn to winter brings elevated mould spore levels, driven by decomposing leaf litter in damp, wooded areas and riverine environments like Petersham Meadows.

The pollen count in Richmond upon Thames today is moderate, driven mainly by Cock's-foot.
