The birch blossom is now followed by the grass season!

In the coming days, the weather forecast promises many hours of sunshine and only the occasional cloud. Together with temperatures of between 15 and 20 degrees Celsius, this means ideal conditions for pollen flight. As we are currently at the transition between the birch- and grass pollen season many allergy sufferers can suffer from symptoms.

The birch blossom is already over in most parts of Burgenland. However, there may still be moderate symptoms due to cross-reactions to the pollen of other birch plants, such as beech trees, oaks, hornbeam and hop hornbeams.

The plane tree, which is often found in urban areas plane tree which is often found in urban areas, has also largely finished flowering and can only provide relevant pollen concentrations in the vicinity of large populations.

On the other hand, the first grasses are already flowering in climatically favoured locations. Tufted grass and bluegrass in particular have already been sighted flowering and can lead to initial pollution. However, these are still limited to the immediate vicinity of the plants. Flowering is not expected to start across the whole area until the weekend or next week.

Lilacs are in bloom and can lead to exposure in the immediate vicinity for people who are sensitised to the pollen of olive trees.

Oilseed rape is also in flower. In order to avoid possible symptoms, people with pollen allergies should avoid the vicinity of rapeseed fields.

In addition to the pollen types mentioned above maple, horse chestnut, sour grasses, walnut and cypress plants are represented in the pollen spectrum. However, they only have a very low allergenic potential.
