About Pollen in Rugby

Rugby’s spring allergy profile, March-May, is dominated by Birch and Oak pollen, peaking around mature trees in Caldecott Park and Rugby School grounds; summer transitions to widespread grass pollen, May-July, originating from River Avon floodplains and surrounding agricultural lands. Rugby’s urban landscape can trap pollen, intensifying localised exposure; late-season outdoor mould spores, prevalent September-November, stem from damp leaf litter decomposition in green spaces like Whitehall Recreation Ground.
