Forecast

The rain is a blessing for pollen allergy sufferers!

The weather forecast promises heavy rainfall in the coming days. This will give allergy sufferers a longer period of relief. Only on Wednesday will the sun shine a little longer, so that the pollen count of dock, grasses and plantain can regain momentum and cause moderate stress. The rain returns on Thursday and slows down the pollen count.

The peak of the oaks- and beech blossom is over and the rain ensures that only low pollen concentrations are reached.

First green alders have started to bloom and are pollinating locally in their subalpine distribution area as soon as the sun appears.

In Vorarlberg, panicle grass, tufted grass and foxtail grass are currently in bloom. The first flowering grasses can also be found at altitudes above 1,000 metres; here, however, the load is lower than in the valleys. Dock and plantain have also started to flower. The rain dampens the pollen count. When the sun shines and the inflorescences dry, moderate concentrations can be reached.

Note: Yellow streaks known as sulphur rain can currently be found in rain puddles. This is pollen from conifers such as spruce, pine and fir trees. From an allergological point of view, this pollen is not relevant. In sunny periods, however, high concentrations can be released into the ambient air, which can lead to mechanical irritation of the conjunctiva and respiratory tract.

In addition to the types of pollen already mentioned, pollen from sedges, horse chestnut, elderberry, legumes, members of the rose family and rushes are present in the air. However, these only have a low allergenic potential.
