About Pollen in Kingston upon Thames

Kingston upon Thames experiences peak tree pollen March-May; Birch and Alder are dominant early spring (March-April) from vast populations in Richmond Park and Bushy Park; Oak pollen follows (April-May) from mature trees across Kingston’s green spaces, including Home Park. Summer (May-July) brings pervasive Grass pollen from River Thames floodplains, local meadows, and open parklands.

Kingston’s urban-green interface, particularly near the Thames, can trap and concentrate pollen; increased humidity near the river may heighten symptom severity. Late autumn-winter (October-January) features elevated Mould spores from damp leaf litter decomposition in parks and riverine areas.
