About Pollen in Gloucester

Birch pollen, late March-April, originates from Gloucester Park and city’s mature trees; Oak pollen follows, April-May, prevalent near Robinswood Hill Country Park fringes and River Severn banks. Grass pollen dominates May-July, primarily from Alney Island’s open spaces, urban green verges, and riverside meadows.

Gloucester’s basin topography and urban structures trap airborne pollen, intensifying local concentrations; prevailing south-westerly winds from rural areas increase overall load. Autumn/Winter, mould spores rise from decaying leaf litter in areas like Barnwood Park and damp canal-side vegetation, persisting through mild, wet periods.

The pollen count in Gloucester today is moderate, driven mainly by Mugwort.
