Birch continues to cause problems!

With a brief interruption on Tuesday, the coming days will be mostly dry and sunny or cloudy. The precipitation expected for Tuesday may dampen the pollen count somewhat in the short term, but otherwise intense pollen counts are to be expected in Vienna over the next few days.

The birch pollen concentrations once again reached high levels at the weekend, but are already showing a downward trend and will probably only rarely reach high concentrations in the coming days, but rather stabilise at a moderate level.

Nevertheless, this is not yet the all-clear for birch pollen allergy sufferers, as in addition to the birch trees that are still in bloom beech, oak, grove and hop hornbeamalso release pollen and can further increase the stress caused by cross-reactions.

The plane tree blossom causes an intensive pollen count in the parks and residential areas of Burgenland. Complaints are particularly likely along plane tree avenues.

In Vienna, many lilac bushes are now also in bloom and can lead to localised symptoms in people who are sensitised to the pollen of this olive tree plant. As the flowers are insect-pollinated, possible exposure is only to be expected in the immediate vicinity of the plants.

In thermally favoured locations, such as sheltered courtyards or parks, the first grasses in flower. These are very localised occurrences that can currently only cause minor pollution in the immediate vicinity. The forecast data for the grass pollen season currently indicates that flowering will start at the beginning of May. These data are still subject to major uncertainties at the beginning of the season and will become more precise over time.

In addition to the pollen types mentioned maplesour grasses and cypress plants are also represented in the pollen spectrum. However, they only have a very low potential for allergic stress.
