About Pollen in Tower Hamlets

Tower Hamlets’ spring allergy season (March-May) features dominant Birch and Oak pollen, originating from mature trees within Victoria Park, Mile End Park, and along the Regents Canal; summer (June-August) brings pervasive Grass pollen from urban lawns, playing fields, and Thames riverbank vegetation.

The built urban environment, particularly denser zones and adjacent to the Thames, can trap airborne pollen, locally increasing concentrations; late autumn (September-November) introduces significant mould spore exposure from decomposing leaf litter in local parks and damp urban pockets.

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