Forecast

A sunny week with a strong early bloomer pollen count awaits us!

The sunny and mild weather continues this week. These conditions are ideal for the pollen count, which is why pollen allergy sufferers need to be prepared for days with a high pollen count. Although short, localised rain showers are forecast for the middle of the week, these will hardly slow down the pollen count.

In the lowlands of Lower Austria, the hazel has passed its flowering peak, but the pollen load will remain at a high level. In the Waldviertel and in the higher altitudes of the industrial and Mostviertel regions, the hazel will only dust more this week and reach its pollen release peak. In parks and gardens, the flowering of tree hazels will now be replaced by that of corkscrew hazels. These can increase localised exposure to hazel pollen.

Grey alder and black alder are currently dusting the flowing and standing waters of Lower Austria. Here, too, people who are sensitised to these trees must be prepared for a strong pollen count and therefore high levels of exposure.

Hazel and alder are closely related to birch. People who are sensitised to birch can therefore be exposed to cross-reactions, even though birch is not yet in flower.

In addition to alder and hazel, pollen from yew, poplar, willow, elm and cypress has also been detected. The expected pollen load of these early-flowering plants is low to moderate in Lower Austria.

From a current perspective, the data from our birch flowering readiness model indicate that it will be reached in the second half of March.
