Pollen Count & Forecast for Cheltenham, Cheltenham

Cheltenham experiences significant seasonal allergies; dominant spring tree pollens, Birch and Oak, are prevalent from March to May, dispersing from mature urban parklands like Pittville Park and Imperial Gardens; summer grass pollen peaks June through July, originating from the River Chelt’s floodplains and surrounding Cotswold meadows. Cheltenham’s valley location, nestled by the Cotswolds, can concentrate airborne pollen, intensifying local impact; autumn’s allergen profile shifts to mould spores, heightened from September onwards, arising from damp leaf litter decomposition in shaded park areas and local woodlands.
