Pollen Count & Forecast for Haringey, Barnet

Haringey’s seasonal allergy profile features prominent spring tree pollens; Birch (March-May) and Oak (April-May) dominate, sourced from mature woodlands including Highgate Wood, Queen’s Wood, and Alexandra Park. Summer brings peak grass pollen (May-July) from extensive meadows and riverine habitats within Tottenham Marshes and along the River Lea corridor.

Urban density can trap pollen, creating localised high concentrations; conversely, expansive parklands and open green spaces facilitate dispersion. Late-season mould spores (August-October, peaking autumn) are prevalent, stemming from decaying leaf litter and damp organic matter in shaded park areas and along watercourses, completing the annual cycle.
