About Pollen in 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.

The pollen count in Swindon today is moderate, driven mainly by Mugwort.
