About Pollen in Luton

Luton’s allergy season commences late March with high Birch pollen from Wardown Park and street trees, peaking April; Oak pollen follows through April-May from Stockwood Park and surrounding woodlands; Grass pollen dominates May-July, peaking June, originating from River Lea floodplains and urban green spaces like Leagrave Park.

The Lea Valley topography often traps pollen, exacerbating symptoms; Autumn sees increased mould spore levels (October-November) from damp leaf litter decomposition in parks and shaded urban areas.

The pollen count in Luton today is HIGH, driven mainly by Mugwort.
