About Pollen in Exeter

Exeter’s spring allergy profile is dominated by Birch pollen, abundant from mature trees within the University of Exeter grounds and city parks (e.g., Northernhay Gardens); Oak pollen follows, prevalent across broader green spaces. Summer transitions to high Grass pollen counts, originating from extensive meadows along the River Exe and Ludwell Valley Park.

The city’s valley topography can concentrate airborne pollen in still, warm conditions. Autumn and winter bring elevated mould spore levels, driven by leaf decomposition in damp parks and riverside areas, notably around Exeter Quay.

The pollen count in Exeter today is V.HI, driven mainly by Mugwort.
