Moderate to high pollen load, on Thursday rain may provide some relief!

The weather forecast for Lower Austria promises us a sunny and dry start to the week. From today's perspective, however, rain is expected to fall in some regions on Thursday. Depending on how intense this rainfall is, it could provide some relief for pollen allergy sufferers. In the sunny phases, however, there may still be moderate to high levels of allergies.

Only in the higher regions of the industrial, cider and forest districts are individual birches. Here, moderate concentrations can still be reached locally. Due to their relationship to the birch family, currently flowering walnut trees, oaks and beeches are affected by cross-reactions.

In Lower Austria, the following continue to bloom manna ash and lilac. Although both are relevant for people with an olive tree allergy, they produce significantly less pollen as they are mainly pollinated by insects. Sensitised people should avoid the immediate vicinity of these trees.

As the plane trees have now been pollinated, only small amounts of pollen could be detected at our measuring points. The horse chestnut blossom continues and can affect people who are sensitised to maple.

Oilseed rape is flowering in the fields. Sensitised people should avoid the area around these yellow-flowering fields, as the exposure can be intense here.

In Lower Austria, flowering panicle, couch grass, cock's foot grasses and foxtail grasses were sighted.

Note: At the moment, a yellowish film of dust can be found on car roofs or window sills. This is pollen from conifers such as spruce, pine and fir trees. From an allergological point of view, it is not relevant. However, as this pollen is present in high concentrations in the ambient air, it can cause mechanical irritation of the conjunctiva and respiratory tract.

In addition to the pollen types already mentioned, maple, larch, rush and cypress pollen is currently also found in the air. However, these only have a low allergenic potential.
