Pollen information for Vienna from 15 September 2025

Unsettled weather may curb pollen count somewhat!

The trend of the past few days continues at the start of the week. On Monday, it will remain warm and dry in late summer, but then clouds will gather and precipitation may occur. Depending on the intensity, allergy sufferers may experience more or less relief.

Ragweed remains the main component of the pollen spectrum, although a clear downward trend can already be observed here. However, as the pollen is classified as highly allergenic, moderate to high levels of exposure must still be expected for affected people.

However, a renewed increase in mugwort pollen in the air must also be expected in the coming days. This is due to later flowering members of this genus, which are now ready to flower.

The concentration of grass pollen in the ambient air remains low. In addition to the later flowering grass species such as dog's tooth grass, this is probably also due to the reed flower in Vienna.

Moderate concentrations of fungal spores are expected in Vienna in the coming days.

Other types of pollen detected in the ambient air are nettle, hemp, hops, plantain and cypress. These are of minor allergological significance.
