About Pollen in Brent

Spring in Brent, Barnet, experiences high Birch and Oak pollen counts, sourced from street trees and local green spaces like Totteridge Valley; summer brings significant grass pollen, prevalent in extensive meadows and riverbanks, notably along the River Brent.

Urban microclimates within Barnet, particularly in sheltered parklands and valleys, can trap and concentrate pollen; late autumn and winter see elevated mould spore levels, driven by dampness and decomposing organic matter in shaded urban environments.

The pollen count in Brent today is moderate, driven mainly by Perennial Ryegrass.
