The birch blossom has passed its peak!

Despite the sunny weather conditions, which would actually allow a lot of pollen to fly, we can probably only expect a moderate amount in Burgenland over the next few days.

Because the birch blossom has already passed its peak and usually only causes low to moderate exposure. In some places, allergy sufferers may also experience additional exposure due to cross-reactions caused by the blossoming of beech, oak and grove- and hop hornbeam as they all belong to the same plant family as the birch.

The blossom of the plane tree is already well advanced. However, considerable stress can still occur along plane tree avenues or other large clusters of this plant.

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

In climatically favoured locations (sunny slopes, green areas in the city), flowering panicle grasses have already been found in isolated cases. panicle grasses have already been sighted. In their vicinity, sensitised allergy sufferers may experience initial symptoms. However, widespread flowering is not expected until the beginning of May.

In rural areas, the first rapeseed fields are in bloom. To avoid possible symptoms, pollen allergy sufferers should avoid being near these fields.

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