Pollen Count & Forecast for Swindon

Swindon’s spring allergy season (March-May) is dominated by Birch and Oak pollen, originating from Lydiard Park, Town Gardens, and urban street trees; late spring through mid-summer (May-July) experiences high Grass pollen counts from Coate Water’s extensive meadows and surrounding rural agricultural land. The town’s urban basin topography can concentrate airborne pollen; autumn (October-November) introduces elevated Mould spore levels, primarily from decaying leaf litter in parks like Queen’s Park and general damp conditions.
