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.
