Pollen Count & Forecast for Greenwich

Greenwich experiences peak tree pollen (Birch, Oak) March-May, originating from Greenwich Park’s mature woodlands, Blackheath’s perimeter trees, and street plantings; summer sees high grass pollen May-July from Greenwich’s extensive green spaces and Thames-side meadows. Urban topography in Greenwich traps pollen, amplifying local concentrations; autumn/winter mould spores from decaying vegetation, particularly near Thames Path damp zones, complete the seasonal profile.
