Pollen Count & Forecast for Barnet

Barnet’s seasonal allergy profile commences early spring (March-April) with high tree pollen from prevalent Birch and Oak, concentrated in urban green spaces like Trent Park and Oak Hill Park; mid-spring (April-May) sees further tree pollen from Plane and Ash street trees; summer (May-July) transitions to peak grass pollen, primarily from extensive meadows within the Dollis Brook Valley Walk and Totteridge Valley.

Pollen levels are influenced by Barnet’s varied topography, with valleys like Dollis Brook potentially trapping airborne particles, while elevated areas near High Barnet facilitate broader dispersal; late autumn (September-November) introduces elevated mould spore counts, stemming from decaying leaf litter in wooded areas and damp conditions, notably around Hadley Wood and Trent Park.
