Forecast

Friendly start to the week with moderate to heavy pollen count, relief from the middle of the week due to a change in the weather!

It will remain sunny and mild in Styria until Wednesday. Under these conditions, the pollen count will be unhindered, so allergy sufferers will have to be prepared for moderate to high levels of pollen. The weather will change on Wednesday evening. It will be rainy, it may snow at higher altitudes and daytime highs will drop below 10 °C. This means relief for allergy sufferers, as the rain washes the pollen out of the surrounding air and the lower temperatures inhibit the release of pollen.

Even in the higher altitudes of Styria, the flowering of the alders and hazels is coming to an end. Moderate pollution is still possible here. However, if the wind direction is right, relevant amounts of pollen can be transported to the lowlands, causing pollution there.

In the lowlands of Styria, the ash trees are now in full bloom and, as long as it remains sunny and mild, will cause moderate to high levels of pollution.

Like the ash tree, the forsythia belongs to the olive family and its pollen can cause cross-reactions. These yellow-flowering heralds of spring are insect-pollinated, which means that only a small amount of pollen is spread by the wind. However, people who are sensitised to olive trees should not place flowering forsythia branches in their homes in order to keep their environment low in allergens.

In the lowlands of Styria willows and poplars have passed their flowering peak, but continue to provide moderate pollen concentrations. At higher altitudes, these two willow plants have not yet reached their full potential, meaning that a high pollen load can occur. The inflorescences of the pussy willow are a traditional Easter decoration. However, allergy sufferers should refrain from using this spring greeting in their homes.

In climatically favoured locations such as sunny south-facing slopes or sheltered courtyards, the first hornbeams and birches are already ready to flower. As long as it remains sunny and mild, the number of these early starters will increase. The immune system of pollen allergy sufferers can react particularly sensitively at the start of the birch pollen season, which can lead to increased stress. However, the change in the weather will provide relief and delay the general start of flowering somewhat. As soon as the weather improves again, a rapid increase in exposure to birch pollen is to be expected.

In addition to the pollen types already mentioned maple, elm, yew and cypress plants are represented in the pollen spectrum. However, they only have a very low potential for allergic reactions.
