About Pollen in Lincoln

Lincoln experiences peak seasonal allergies driven by specific local flora and geography. Birch and Oak pollen dominate March-May, abundant in Lincoln Arboretum and uphill areas surrounding Lincoln Cathedral and Castle grounds; Grass pollen peaks May-July, prevalent from River Witham floodplains, Hartsholme Country Park meadows, and surrounding agricultural lands.

The Lincoln Edge escarpment influences pollen dispersion; the urban basin traps airborne particulates, increasing localised concentrations. Autumn mould spores elevate September-November, stemming from damp leaf litter in areas like Boultham Park and general decomposing vegetation.

The pollen count in Lincoln today is moderate, driven mainly by Mugwort.
