About Pollen in Suzhou

Suzhou’s spring allergy season (March-May) is dominated by Willow and Poplar pollen; Willow (Salix) prolific near Jinji Lake; Poplar (Populus) widespread around the Humble Administrator’s Garden. Pine (Pinus) contributes significantly from the slopes of Tiger Hill. Summer (June-August) has high Grass (Poaceae) and Mugwort (Artemisia) pollen levels, originating from the banks of the Grand Canal and Taihu Lake wetlands.

The city’s extensive canal network and high humidity trap airborne particles; narrow alleys in the Gusu District create stagnant air pockets. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from the damp environments of historic gardens and water-side stone structures.
