Pollen Count & Forecast for Innsbruck

Innsbruck’s spring allergy season (February-May) is dominated by Hazel (Corylus) and Alder (Alnus); these trees are common along the Inn River banks and Nordkette slopes. Birch (Betula) and Ash (Fraxinus) are concentrated near the Hofgarten and Bergisel. Summer (May-August) has high Grass (Poaceae) levels; pollen travels from mountain meadows on the Patscherkofel and alpine pastures. Mugwort (Artemisia) is present in late summer.

Steep mountain topography creates valley inversions; these trap pollen in the city basin. Foehn winds carry allergens from the south through the Wipp Valley. Autumn has high Mould (Alternaria, Cladosporium) spore counts; these come from damp leaf litter in the Karwendel forests and areas near the Sill River.
