Pollen Count & Forecast for Aylesbury, Buckinghamshire

Aylesbury’s seasonal allergy profile begins March-April with Birch pollen, dominating Vale Park and urban green spaces; Oak and Plane trees follow April-May from surrounding woodlands and town centre avenues. Grass pollen peaks intensely May-July, originating from expansive River Thame floodplains and local roadside verges.

The Thame valley’s natural topography can funnel and concentrate airborne allergens, particularly in warm, dry conditions. Late-season Mould spores intensify September-November, driven by damp leaf litter decomposition within parklands and shaded urban zones, persisting until first hard frosts.
