Increase in pollen count in the east, continued relief in the west!

At the beginning of the second half of the week, a genoa low and a cold front create weather conditions that largely prevent the pollen count. Towards the weekend, however, at least the sun will be able to assert itself a little more in the eastern half of Austria and it will stop raining. As a result, the pollen count will increase in intensity again and can lead to intense pollen counts. In the west, the precipitation will last a little longer, so that persistent relief is also to be expected there.

We are at the beginning of the main stress phase of the grass season. Although the first relevant loads have already been registered in recent weeks, the weather conditions ensured that only a small amount of pollen was released into the ambient air. In general, however, the development of the grasses has benefited from the recent rainfall, meaning that an above-average grass pollen season is expected. While the expected levels in western Austria will stabilise at moderate values due to the weather, in the eastern half of the country it will be mainly smooth oat, foxtail, bunch and panicle grasses, as well as grasses that will cause high levels. Rye may also bloom on some arable land.

In meadows, dock and plantain may bloom occasionally and cause additional stress.

Oak and walnut pollen are only rarely detectable in the air, but can still lead to stress for birch pollen allergy sufferers.

Green alder blossoms in the mountains and can cause allergic symptoms in the immediate vicinity. However, as it will remain very cold there in the coming days, not much pollen is to be expected. However, if the temperatures are higher locally, relevant amounts of pollen may still be released, causing localised discomfort. However, it is not expected to reach the valleys in the coming days.

The horse chestnut, which is often planted as an avenue and park tree, is still flowering. As this plant is pollinated by insects, its pollen rarely gets into the air and is therefore of little allergological relevance.

The lime and vine buds are already well developed, but still need a few more hours of sunshine before they blossom. From an allergological point of view, however, the pollen from these plants poses little danger. Only the scent of lime trees can cause irritation in sensitive people.

The pollen of the first flowering stinging nettles can also be detected in our measuring stations, but it too has only a low potential to cause allergic reactions.

The first relevant concentrations of fungal spores are registered at our measuring points in the lowlands and valleys. For the time being, however, they only reach low concentrations in the ambient air.

Other types of pollen in the ambient air: umbellifers, yew, spruce, pine, elder, mulberry, cloves, robinia, sour grasses, fir and cypress. These are of minor allergological importance.
