Pollen Count & Forecast for Essen

Essen’s spring allergy season (March-May) is dominated by Birch and Alder pollen; Birch (Betula) prolific in Grugapark and the Schellenberger Wald; Alder (Alnus) widespread along Ruhr riverbanks. Hazel (Corylus) contributes to early spring counts from the Stadtwald. Summer (May-August) sees high Grass (Poaceae) pollen levels, originating from meadows around the Baldeneysee and Heisingen.

The Ruhr Valley terrain traps air masses; hills and urban streets hold pollen in low-lying areas. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from wet leaf litter in the Grugapark and damp environments near the river.
