About Pollen in Southwark

Spring brings dominant Birch and Oak pollen from Southwark Park, Burgess Park, and mature street trees; summer features peak Grass pollen, prevalent along Thames riverbanks and urban green spaces. Dense urban infrastructure, notably around London Bridge and Elephant & Castle, traps and concentrates airborne pollen; late autumn to winter, mould spores proliferate from damp foliage decomposition within parks and shaded residential zones.

The pollen count in Southwark today is HIGH, driven mainly by Giant Ragweed.
