A spring-like weekend is just around the corner and the pollen will fly unhindered!

From the Waldviertel to the Schneeberg, the weather forecast promises spring-like temperatures and sunny to cloudy conditions that will allow pollen to fly unhindered. Although hazel and alder are in the process of flowering, but allergy-relevant pollen concentrations continue to be recorded at our monitoring centres. Now the blossoming of the ash trees flowering, which is why sensitised people need to be prepared for moderate to high levels. At the beginning of the coming week, the weather forecast promises rainfall for the Most and Industrieviertel. Depending on how heavy this precipitation is, it could provide some relief for pollen allergy sufferers.

The flowering of hazel and alder has now also peaked in the Waldviertel and at higher altitudes in the Limestone Alps. For allergy sufferers who are sensitised to these two early bloomers, however, this does not mean the end of their exposure. This is because pollen that has already sunk to the ground can be stirred up again by the wind and pose a threat. Abundant rainfall would prevent this. This weekend, however, it will remain dry in Lower Austria.

The number of ash trees in bloom has increased over the past few days, meaning that sensitised people must be prepared for a moderate to high pollen load.

The fluffy catkins of the sal willow, commonly known as pussy willow, are also currently in bloom. Their pollen is categorised as moderately allergenic. Allergy sufferers who are allergic to willow and poplar should not put the branches of this pre-Easter herald of spring on their Easter table.

In the pollen spectrum maple, poplar, elm, yew and cypress plants have been detected. In Lower Austria, the pollen load from these early-flowering plants is low to moderate.

The catkins of the birch are still firmly closed. The birch blossom is not expected to start this weekend. From a current perspective, the data from our birch flowering readiness model indicate that it will be reached in the second half of March.
