Pollen information for Austria from 04 May 2026
Precipitation provides relief in western Austria!
A weekend dominated by sunshine will now be followed by a few days of more changeable conditions. Coming from the west, bad weather with rain and thunderstorms will spread across the country in the coming days. Depending on the intensity of the precipitation, allergy sufferers may experience relief, at least in the short term. People who are particularly sensitive to grass pollen will benefit from this brief change in the weather, as only low concentrations of pollen can be expected in the air when it rains, whereas moderate concentrations are possible on sunny days.
The main culprits for the current grass pollen levels are meadow grasses, switch grasses, tufted grasses and foxtail grasses. According to our modelling, the grasses in most regions should already be ready for flowering or at least close to it. Due to the lack of precipitation in April, this year's grass pollen season is expected to be slightly below average to average in intensity.
In the meadow aspect, additional burdens from floweringdock and plantain are possible.
Note: A yellowish film of dust can currently 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.
The birch blossom has now passed its peak throughout the country, so that even at higher altitudes only low to moderate levels are usually reached.
The concentrations of beech, oak, hornbeamresp.hop hornbeamare already on the decline, but can still cause cross-reactions in birch pollen allergy sufferers.
The white flakes in the air are the seeds and seed hairs of the poplar. Their flight usually coincides with the start of grass flowering, but unlike grass pollen, they cannot cause allergic symptoms.
People who are sensitised to the pollen of olive trees must continue to expect symptoms in the coming days due to the flowering of the manna ashbut also to lilacs in the immediate vicinity.
In rural areas, rape fields are in bloom. To avoid possible symptoms, pollen allergy sufferers should avoid being near these fields.
The lime trees that are often planted in gardens are also close to flowering and may start to bloom in the coming days if the conditions are right. Their flowers are adapted to insect pollination and are therefore rarely found in the air, although the scent of the flowers can irritate the airways of sensitive people.
In addition to the pollen types mentioned above, umbellifers, ginkgo, mulberry and horse chestnut are also currently in bloom, horse chestnutsour grasses, walnut and cypress plants are represented in the pollen spectrum. However, they only have a very low allergenic potential.
