Pollen Count & Forecast for Preston

Preston, Canterbury experiences peak tree pollen March-May, predominantly Birch and Oak from surrounding deciduous woodlands and village hedgerows; grass pollen dominates May-July, originating from extensive local agricultural fields and Little Stour river floodplains.

The low-lying Little Stour valley significantly influences pollen dispersion, potentially trapping concentrations. Late-season mould spores are prevalent September-November, driven by decomposing leaf litter in damp woodland areas and the humid river environment.
