Rain is bringing some relief to Vorarlberg!

There will be heavy rain in Vorarlberg over the coming days. The rain washes the pollen out of the air and prevents it from being released. For those with pollen allergies, the rainfall is therefore a blessing, as it keeps pollen levels low. However, if the sun shines long enough to dry out the grass inflorescences, pollen levels may rise in the vicinity of flowering meadows.

Grass flowering is progressing in the lowlands of Vorarlberg. They are also flowering at higher altitudes. At the moment, couch grass, brome grass, false oat grass, honey grass, cock's foot grass, false barley, rye grass and foxtail grass are flowering in the region. Rye is flowering and usually releases pollen in the morning. As its pollen is relatively large and does not travel far, high pollen counts only occur during sunny spells in the immediate vicinity of rye fields. Nettles, plantain and sorrel are also flowering and can increase pollen levels. 

In its range, which lies above 1,000 metres above sea level, the green alder continues to flower. This is also where the main concentration of pollen is found. However, rain keeps pollen concentrations low and prevents long-distance transport to the lowlands. For allergy sufferers who are sensitised to birch trees, this pollen is relevant as cross-reactions may occur.

In the valleys of Vorarlberg, lime trees are now in bloom. As their flowers are adapted to insect pollination, they are generally rarely found in the air. However, their floral scent can irritate the airways of sensitive individuals.

Fungal spores are now becoming more significant for allergy sufferers. The first quantities relevant to allergy sufferers are already present in the air. Fungi release spores more frequently, particularly after rain.

In addition to the pollen types already mentioned, pollen from pine, spruce, umbellifers, elder, legumes and cypresses is currently also present in the pollen spectrum. However, these pose only a very low allergenic risk.
