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.
