Pollen Count & Forecast for Slough

Spring in Slough is dominated by Birch and Oak pollen, originating from mature trees within Upton Court Park, Herschel Park, and urban streetscapes; Alder and Willow contribute near the Jubilee River and Grand Union Canal. Summer sees high Grass pollen from extensive sports fields, park verges (e.g., Salt Hill Park), and agricultural fringes.

Slough’s built environment can concentrate airborne allergens locally; prevailing westerly winds import additional tree and grass pollen from wider Buckinghamshire. Late autumn into early winter elevates Mould spore counts, stemming from decaying leaf litter within parks and damp areas adjacent to the Jubilee River and canals.
