About Pollen in Salisbury

Salisbury’s spring allergy profile (March-May) is dominated by Birch and Oak pollen, originating from mature trees within Churchill Gardens, Victoria Park, Queen Elizabeth Gardens, and city-edge woodlands; summer (May-July) sees high grass pollen levels, primarily from the expansive water meadows along the Rivers Avon and Nadder, and urban verges.

The city’s basin-like topography and river valleys can concentrate airborne particulates, intensifying local pollen exposure; late-season (September-November) elevated mould spore counts are prevalent, particularly in damp, shaded areas near the riverbanks and decomposing leaf litter in parklands.
