Pollen information for Vorarlberg from 15 September 2025
Precipitation is preventing the pollen count!
It will be sunny in Vorarlberg at the start of the week. From Monday evening, however, thunderstorms will form, which will rain off by Tuesday morning. This precipitation will bring some relief to allergy sufferers. The weather will improve again from Wednesday. The pollen concentration will remain at a low level, while the fungal spore levels will fluctuate between moderate and high.
In Vorarlberg, there are still individual specimens of mugwort in flower. However, these hardly release any pollen. Sensitised persons should nevertheless avoid direct contact with mugwort.
The Canadian goldenrod is currently flowering in the valleys of Vorarlberg. The pollen of this yellow-flowering composite plant can lead to cross-reactions in people who are sensitised to mugwort or ragweed.
Reeds are also currently flowering around lakes and bodies of water. People who are sensitised to grasses should avoid dense stands. 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.
