Pollen Count & Forecast for Łódź

Łódź’s spring allergy season (March-May) is dominated by Birch and Oak pollen; Birch (Betula) prolific in Las Łagiewnicki; Oak (Quercus) widespread across Piłsudskiego Park. Ash (Fraxinus) contributes significantly from Klepacza Park and along the Jasień River. Summer (June-August) sees high Grass (Poaceae) pollen levels, originating from open fields near Lublinek and the Ner River valley.

Dense 19th-century street canyons and tenement blocks trap pollen in the city center, creating localised high concentrations. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from decomposing leaf litter in urban green spaces and damp basements.
