The sun will come out again at the weekend; low pollen levels are expected!

The weather is set to improve in the second half of the week. Only on Thursday might there still be some light rain in the Bludenz region. On Saturday and Sunday, the sun will shine again and maximum temperatures could reach up to 24 °C. On the one hand, the rain has washed the pollen out of the air; on the other hand, we are now at the end of the flowering season for most herbaceous plants. For people with pollen allergies, this usually means only low pollen levels. However, this does not apply to people who are sensitised to fungal spores, as spore counts remain at moderate to high levels.

The flowering of the invasive and highly allergenic ragweed continues to progress. Even just a few pollen grains per cubic metre of air can trigger symptoms. Ragweed is found in Vorarlberg along the main transport routes in the Rhine Valley. At the end of August, there was increased long-distance transport of ragweed pollen from the west. This led to high pollen levels in Vorarlberg. Long-distance transport of ragweed pollen is unlikely in the coming days.

Canadian goldenrod is also in flower. For people with allergies who are sensitised to mugwort or ragweed, it can trigger cross-reactions.

In addition, grasses, stinging nettle, plantain and cypresses were detected in the pollen spectrum. However, these were present only in low concentrations.
