Situation and medium-term forecast for

Issued on July 11, 2024

The grass season is now followed by the flowering period of mugwort!

In the lowlands and valleys, exposure to grass pollen is continuing to decrease, with only isolated higher concentrations to be expected at higher altitudes.
In contrast, the flowering period of mugwort has already begun in some places and can lead to initial local exposure.

While rain is to be expected up to and including Saturday, especially in the west of the country, which may dampen the pollen count, almost unclouded sunshine will ensure better conditions in the east.

The concentration of grass pollen in the air is already declining throughout Austria. In the lowlands and valleys, they only reach low to moderate levels, while at higher altitudes or in climatically less favorable locations they can still reach high levels for a short time.

Dock and plantain are still recorded in small quantities.

As the grass pollen season winds down, the next period of burden for pollen allergy sufferers, the flowering of "weeds", is already approaching. As usual, this season begins with the flowering of mugwort, which can already bloom in warm locations. Although pollen from these plants is only rarely registered at our measuring stations, the first low levels of allergenic burden can already occur locally.

The flowering of green alder, which occurs at higher altitudes, is coming to an end. Only rarely are pollen concentrations registered that exceed the threshold for allergenic burden.

Pollen from nettle family can also still be detected in moderate to high concentrations in the air, but from an allergological point of view they only pose a low risk.

Fungal spores are still registered in moderate to high concentrations and can lead to intensive exposure, especially after rainfall.

Other less allergologically relevant types of pollen in the ambient air: rushes, lime, sour grasses and cypresses.
