Pollen Count & Forecast for Maidenhead

Maidenhead experiences peak spring allergies from late February through May, predominantly Birch and Oak pollen originating from Ockwells Park, Braywick Nature Centre, and Thames-side arboreal corridors. Summer’s primary allergen, Grass pollen, peaks June-July, prevalent across river floodplains, local meadows, and urban green spaces. The low-lying Thames Valley topography and extensive local green infrastructure can significantly concentrate airborne pollen. Late autumn and winter see elevated Mould spore levels, exacerbated by damp leaf litter decomposition in shaded parks, such as Kidwells Park, and along waterway banks.
