Pollen Count & Forecast for Plymouth

Plymouth’s spring (March-May) sees dominant tree pollen: Birch, prevalent in Central Park and streetscapes; Oak, widespread across Saltram Estate and Plym Valley woodlands. Summer (May-July) brings high Grass pollen from urban green spaces, roadside verges, and the extensive Plym and Tamar river valleys.

The city’s topography and coastal winds modulate pollen exposure; urban canyons and sheltered areas can concentrate allergens despite periodic sea breeze dispersion. Autumn (August-November) exhibits elevated Mould spore levels, fostered by Plymouth’s prevalent damp conditions and decaying leaf litter in parks and wooded fringes.
