About Pollen in High Wycombe

High Wycombe’s spring, March-May, experiences peak Birch and Oak pollen, originating from mature trees within The Rye, Hughenden Park, and surrounding Chiltern woodlands; summer, May-July, is dominated by high Grass pollen, widespread across Holywell Mead, The Rye’s meadows, and River Wye banks. The town’s Wycombe Valley topography often traps airborne pollen, intensifying local concentrations; late season, September-November, sees elevated Mould spore levels from damp leaf litter and decomposition prevalent in local parklands and wooded residential zones.

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