Pollen Count & Forecast for Shrewsbury

Shrewsbury’s primary spring allergens, Birch and Oak, dominate March through May, emanating from The Quarry Park, local urban green spaces, and River Severn’s wooded banks; Grass pollen peaks May to July, sourced from flood plain meadows along the Severn and peripheral agricultural land.

The Severn’s looping geography and surrounding topography can create localised pollen trapping, exacerbated by dry, windy conditions; late season, September through November, Mould spores increase due to damp leaf litter decomposition in wooded areas and elevated riverine humidity.
