Birch in full bloom - very high load, especially in the mountainous regions

The warm temperatures and dry weather have caused the birch blossoms to literally explode. The extremely high proportion of birch and ash pollen leads to extremely severe symptoms for birch pollen allergy sufferers.

While the peak of the birch and ash blossom is likely to be passed soon in the lowlands, it is still to come at higher altitudes. Only the forecast rain showers could flush out the pollen and provide temporary relief.

The first sweet grasses have started to bloom in the foothills of the Alps, and sensitive people should expect increasing symptoms depending on the weather. In the mountain meadows, the grasses will start flowering a few days later.

Also in the pollen spectrum: oak, hornbeam, copper beech, sour grasses, larch
