Pollen Count & Forecast for Bristol, Bath and North East Somerset

Bristol’s allergy profile sees early spring (March-April) dominated by tree pollen: Birch and Hazel from Leigh Woods and Clifton Downs; Oak pollen follows into May across Ashton Court Estate and Blaise Castle. Summer (May-July) brings widespread Grass pollen from urban green spaces like Brandon Hill, Victoria Park, and River Avon meadows.

The city’s valley topography, particularly around the Avon Gorge, traps pollen, exacerbating symptoms in central areas; autumn (Sept-Nov) introduces mould spores, primarily from decomposing leaf litter and damp conditions prevalent in shaded parks and garden environments.
