Brief relief for allergy sufferers on Tuesday!

During the first half of the week, dry weather conditions will dominate in most parts of the country, even if the sun is often overcast. On Tuesday, it may rain in many places, which could reduce the impact on allergy sufferers somewhat. In the far south and west of the country, it is most likely to remain dry and therefore the likelihood of allergic reactions is also high.

In the lowlands, the birch pollen season has clearly passed its peak, so only moderate birch pollen concentrations can be expected there. As the altitude rises, however, higher concentrations can still be expected, which can be attributed to a slightly delayed vegetation period due to lower temperatures.

Due to the flowering of beech, oak, hornbeam and hop hornbeam allergy sufferers who are sensitised to birch pollen but continue to suffer from more intense cross-reactions.

The ash blossom has already come to an end in the lowlands. In less thermally favoured regions, relevant pollen counts may still occur. But even in the lowlands, the all-clear cannot yet be given, as lilacs, which also belong to the olive family, are often already in bloom there. However, its flowers are insect-pollinated and its pollen is therefore less likely to be found in the pollen spectrum of the ambient air.

In urban areas, there are also plane trees are also in bloom in urban areas and can continue to cause considerable pollen counts and the associated pollution.

In thermally favoured locations, flowering panicle and panicle and tufted grasses have already been sighted. Although they can already release pollen, it will take until the beginning of May before they are ready to flower across the board, according to our modelling calculations.

In addition to the aforementioned pollen types, maple, sour grasses, sescens and cypresses are also currently in bloom. cypress plants are also represented in the pollen spectrum. However, they only have a very low allergenic potential.
