About Pollen in Perth

Perth’s spring allergy season (March-May) is dominated by Birch and Alder pollen, originating from North Inch, South Inch, and Kinnoull Hill’s deciduous woodlands; Oak and Willow follow from urban green spaces and River Tay riparian zones. Summer (June-August) brings peak Grass pollen from extensive Tay floodplains and the expansive North Inch parkland.

The city’s valley topography, nestled between Moncreiffe Hill and Kinnoull Hill, frequently traps airborne pollen, amplifying local concentrations; late autumn/winter (September-November+) sees prevalent Mould spores due to damp conditions, decomposing leaf litter in local parks and near the River Tay.

The pollen count in Perth today is MED, driven mainly by Stinging Nettle.
