Forecast

Quiet start to the week, from Wednesday onwards the airborne pollen concentrations will increase!

In Lower Austria, the start of the week will be changeable and temperatures will remain below 10 °C. This will slow down the pollen count for the time being. From Wednesday, daily highs will rise above 10°C again and it will remain mainly dry. As a result, the pollen count will rapidly increase in intensity, meaning that pollen allergy sufferers will have to prepare themselves for a significantly higher level of stress.

The flowering of ash, poplar and willow continues to progress in Lower Austria. As soon as the sun comes out, moderate pollen concentrations are possible, and even high concentrations in the immediate vicinity of these trees.

Allergy sufferers who are sensitised to olive or willow trees should refrain from using flowering forsythia or pussy willow branches as indoor decorations at Easter, as these can lead to additional stress.

The cold and rainy weather has increased the dusting of birch and hornbeams so far. An above-average number of catkins have been observed on the birch trees. As the weather improves from Wednesday, the number of trees ready to flower will increase rapidly. Therefore, a rapid increase in pollen concentrations is to be expected in friendlier weather, especially for allergy sufferers with sensitisation to birch plants.

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