About Pollen in Coventry

Coventry’s allergy profile peaks with spring tree pollen; March-April sees high Birch pollen from urban green spaces like War Memorial Park and Coombe Abbey Park, followed by Oak and Sycamore through May from the wider green belt; June-July brings dominant grass pollen, prevalent across the city’s recreational fields and River Sherbourne’s naturalised banks.

Urbanisation and built-up areas can trap pollen, exacerbating local concentrations; high humidity often elevates mould spore counts from autumn leaf decomposition in city parks and damp residential areas, continuing into winter.
