About Pollen in Stratford-upon-Avon

Stratford-upon-Avon experiences distinct seasonal allergy profiles: Early spring presents high Birch and Ash pollen, prevalent from urban green spaces and street trees around Bancroft Gardens and Holy Trinity; late spring sees significant Oak pollen, originating from local woodlands including areas near Shottery. Summer brings dominant Grass pollen, primarily from River Avon floodplains and surrounding agricultural meadows. The town’s valley topography and urban-rural interface can concentrate airborne allergens; autumn concludes with elevated Mould spore counts, originating from damp leaf litter and decaying organic matter across parks and riverside areas.
