Situation and medium-term forecast for

Issued on July 08, 2024

The heavy loads of grasses are over in the lowlands, mugwort is not yet getting into our pollen traps!

The grasses have now peaked in the lower regions of Styria, so the amount of pollen released is now decreasing in these regions. Furthermore, most meadows were mowed during the fine weather phase. For this reason, only brief exceedances of the irritation threshold are to be expected in urban areas, which will only be mild to moderate at most. The only exceptions are local thunderstorms, which can lead to the bursting of pollen grains and thus irritate sensitive people particularly strongly. Please note our thunderstorm warning, which is also available in the Pollen+ app.

For people who suffer from grass pollen allergies, it is now important to avoid areas with late-flowering grass species such as forest edges, forest roads or forest slopes. Large amounts of pollen can still be released here. Alpine meadows and mountain pastures between 1500 and 2000 meters above sea level can also be exposed to high levels of grass pollen. We recommend avoiding these areas, especially in the morning.

Dock and plantain can also exacerbate the expected stress in meadows.

The current weather conditions favor the production and release of fungal spores, especially in cereal-growing regions. Please note that there may currently be heavy contamination in the vicinity of the fields.

In mountainous areas, the blossoming of green alder can lead to stress for birch pollen allergy sufferers.

The sweet chestnut now only causes minor exposure. The pollen of this tree species, which is often planted in gardens and parks, can also cause symptoms in birch p ollen allergy sufferers due to cross-reactions.

Pollen from the less allergologically relevant stinging nettle plant is also registered at our measuring stations.

Other less allergologically relevant types of pollen in the ambient air: bee willow, elderberry, lime, cattail and sour grasses.
