Weather-related breather in the next few days!

The current weather conditions are leading to a noticeable decrease in pollen count. Although the birch pollen season has already peaked in the lowlands and is gradually coming to an end, larger amounts of birch pollen are possible in the air under certain conditions, such as strong northerly winds. However, the cold front expected for this week will significantly reduce the overall pollen load.

Beech and oak trees are in peak bloom and can lead to high pollen counts on sunny and dry days. However, due to the current weather forecast, the exposure to beech and oak pollen will decrease significantly this week. It should be noted that birch pollen allergy sufferers can also react to beech and oak pollen, which can lead to more severe symptoms.

Exposure to sycamore pollen has fallen sharply in urban areas. In streets with plane tree avenues and large parks, even higher levels can occur locally, but the pollen count is no longer higher across the board.

The main flowering of grasses in the lowlands will not yet begin this week due to the current weather conditions. Some allergologically relevant grass species are already flowering in thermally favorable locations, but the cold front is preventing a higher pollen load. In most regions, there is still no widespread pollen release, so grass pollen concentrations are usually still below the irritation threshold. Only particularly sensitive people are already reacting with symptoms.

The spruce pollen count has also begun. Spruce pollen will dominate the pollen count in large parts of Lower Austria over the next few days (yellow pollen on smooth surfaces).
What else is in our pollen traps? For allergy sufferers, hardly any relevant amounts ofjuniper, elm, rush, ginkgo, sorrel, larch and maple.

We expect the grasses to start flowering across the board in St. Pölten and Wiener Neustadt on 28.04.2024!
