Pollen forecast for Vorarlberg, 21 September 2026
The pollen season is drawing to a close, but fungal spores remain a major problem!
The coming week will start off cloudy but pleasant and dry. Over the next few days, temperatures will mostly hover around 20 °C. The pollen season is well advanced and drawing to a close, as most herbaceous, allergy-causing plants have already finished flowering. Only a few scattered specimens of ragweed, mugwort, grasses, stinging nettles and plantain are still in flower. As autumn begins, fungal spore concentrations will continue to reach moderate to high levels.
Canadian goldenrod is also still flowering in Vorarlberg. For people with allergies who are sensitised to mugwort or ragweed, it can trigger cross-reactions. People with allergies should avoid dense stands of this plant.
