Pollen Count & Forecast for Grimsby

Grimsby experiences peak tree pollen from March to May, primarily Birch and Oak, originating from People’s Park, Grant Thorold Park, and residential street trees; Grass pollen dominates May through July, sourced from River Freshney embankments, surrounding agricultural fields, and urban green verges.

Grimsby’s coastal proximity and flat landscape modify pollen dispersal; sea breezes can clear, yet urban corridors and sheltered areas accumulate. Late autumn brings heightened mould spore counts, September-November, due to damp leaf decomposition in Grimsby’s parklands and shaded urban areas.
