Pollen Count & Forecast for Southampton

Southampton’s allergy profile sees peak Birch and Oak pollen March-May, originating from mature trees across Southampton Common and urban parkland; late-May through July brings high grass pollen from River Itchen/Test floodplains and Eastleigh’s surrounding meadows. Coastal proximity and urban density can concentrate airborne allergens, intensifying local pollen counts; autumn (September-November) introduces elevated mould spores from decaying leaf litter in damp parkland and humid riverine environments.
