Pollen information for Vorarlberg from 26 June 2025

Thunder and lightning in the middle of the week, thunderstorm asthma can be an additional burden!!!

Thunderstorms will descend on Vorarlberg on Thursday. The rest of the weekend will be mostly dry and hot. These are good conditions for the pollen count, which will be moderate to severe.

During thunderstorms, sudden changes in humidity and air pressure can cause pollen to split into tiny particles that penetrate deep into the lungs. This can trigger severe allergic reactions or asthma attacks - a phenomenon known as thunderstorm asthma. Even though rain usually brings short-term relief, allergy sufferers should stay indoors during thunderstorms and keep windows closed to minimise the risk.

The peak of the grass pollen season is over. For allergy sufferers who are sensitised to grasses, however, this hardly means any relief, as couch grass, horse grass, ryegrass and ryegrass continue to bloom. Flowering grasses can also be found in forests and at altitudes above 1500 metres, so these are not places to avoid allergens.

Dock and plantain also bloom and can cause additional stress near meadows. Stinging nettles also bloom and their pollen can irritate sensitised people.

Lime trees bloom in avenues, parks and forests. Its pollen is hardly relevant from an allergological point of view, but the scent of its flowers can cause irritation in sensitive people.

In the Vorarlberg Alps, the green alder is still in bloom, but it has already passed its peak. People who are sensitised to birch plants must continue to expect exposure when hiking in the Vorarlberg Alps. Long-distance transport of green alder pollen into the valleys is possible and can cause additional stress here.

People who are sensitised to olive trees should avoid direct contact with privet bushes.

Fungal spores are expected in moderate to high concentrations in the ambient air in the coming days.

Other types of pollen in the ambient air: umbellifers, goosefoot and buttercup plants as well as clove plants, sour grasses, vines and cypress plants. These are of minor allergological importance.
