Pollen information for Vorarlberg from 11 September 2025

Precipitation prevents the pollen dispersal!

It will remain changeable in the second half of the week. While the rain washes pollen and fungal spores out of the air and thus provides relief for allergy sufferers, moderate to high concentrations of fungal spores can still be reached during sunny periods.

Some mugwort plants are still in flower. However, allergy-relevant pollen concentrations are no longer reached. Sensitised people should still avoid direct contact with mugwort.

The Canadian goldenrod is currently flowering in the Ländle. The pollen of this yellow-flowering composite plant can lead to cross-reactions in people who are sensitised to mugwort or ragweed.

The reed flowers in Vorarlberg. Dense stands should be avoided by people who are sensitised to grasses. From the valleys to the mountain pastures, flowering grasses can still be found occasionally. However, these are only slightly irritating. The flowering of nettles and plantain is also coming to an end. However, they can still cause additional problems.

Allergy sufferers who are sensitised to fungal spores can expect relief during the rainfall. However, as soon as the rain stops, the concentrations of fungal spores in the ambient air can increase for a short time. At higher altitudes and above the tree line, the levels of fungal spores are noticeably lower.

Pollen from umbellifers, ivy, hemp, hops, balsam, goosefoot and cypress plants have also been detected in the ambient air. These are of minor allergological significance.
