About Pollen in Islington

Islington/Hackney experiences peak spring allergen burden from March-May: Birch pollen, abundant from street trees, Highbury Fields, and Clissold Park; Oak pollen follows April-June, dense in larger parkland. Summer brings dominant grass pollen May-July from Finsbury Park’s open areas, local green spaces, and Regent’s Canal banks.

Urban architecture creates microclimates, trapping and concentrating pollen at street level; late-season mould spores, peaking autumn-winter, are elevated by decaying leaf litter and persistent humidity along the New River Walk and Regent’s Canal.

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