Pollen Count & Forecast for Havering

Havering’s allergy season begins with Birch pollen (late March-April) from mature trees in Raphael Park and Romford’s Cottons Park; Oak pollen (April-May) follows, prevalent in Hornchurch Country Park and Bedfords Park; summer’s peak is Grass pollen (late May-July), widespread across public green spaces and riverine meadows of the Ingrebourne and River Rom.

Urban topography across Havering, notably around central Romford, can trap and concentrate airborne pollen; late-season allergy concerns pivot to Mould spores (August-October), exacerbated by damp leaf litter decomposition within Thames Chase Community Forest and water-adjacent parklands like Dagenham Chase.
