The rain slows down the pollen count!

It rains heavily in Styria at the beginning of the week. This is a relief for allergy sufferers, as the rain washes the pollen out of the air and prevents it from being stirred up again. On Wednesdays and Thursdays, the sun shines again in large parts of Styria. This allows the pollen concentrations to rise agian. Moderate amounts of pollen are usually released during these sunny phases.

Now the flowering of the straggler birches in the higher altitudes of Styria. Instead, the first green alders are beginning to blossom. The rainy weather in the coming days will prevent the long-distance transport from the mountains to the lowlands. The blossoming of beech, oak and walnut is coming to an end. Due to their relationship to the birch family, cross-reactions can occur.

The following are currently in bloom in Styria Foxtail, tufted and panicle grasses. The first flowering grasses can also be found at higher altitudes. In the mountains, however, the grass pollen count is still lower than in the lowlands. The rain will dampen the grass pollen count. As soon as the sun comes out and the inflorescences dry out, moderate to high levels can be reached, especially near meadows and roadsides. The following are also currently flowering in the meadows dock and plantain which can increase the pollution.

Note: Yellow streaks, known as sulphur rain, can currently be found in rain puddles. This is pollen from conifers such as spruce, pine and fir trees. From an allergological point of view, this pollen is not relevant. In sunny periods, however, high concentrations can be released into the ambient air, which can lead to mechanical irritation of the conjunctiva and respiratory tract.

In addition to the types of pollen already mentioned, pollen from sedges, horse chestnut, elderberry, legumes, members of the rose family and rushes are present in the air. However, these only have a low allergenic potential.
