About Pollen in Norwich

Spring in Norwich experiences dominant tree pollen, primarily Birch and Oak, originating from mature specimens within Eaton Park, Earlham Park, and UEA grounds from March through May; summer brings high grass pollen levels, particularly from the extensive meadows bordering the River Wensum and Broadland waterways, peaking June to August.

Norwich’s urban topography can locally concentrate airborne pollen; the Broadland’s damp, low-lying areas, especially along the Wensum valley, elevate late-season fungal spore (mould) counts, peaking with autumnal leaf decomposition.

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