About Pollen in Guildford

Guildford’s spring (March-May) brings peak Birch and Oak pollen from extensive woodlands (Chantry Wood) and urban green spaces (Stoke Park), plus residential trees; summer (May-July) is dominated by Grass pollen, sourced from River Wey meadows, unmanaged green spaces, and surrounding agricultural land.

Sheltered valleys around The Mount and urban-forest interfaces can trap pollen, elevating local concentrations; autumn (September-November) introduces elevated Mould spore levels, primarily from damp leaf litter decomposition in wooded areas and along the Wey Navigation.

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