About Pollen in 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.

The pollen count in Plymouth today is V.HI, driven mainly by Mugwort.
