Situation and medium-term forecast

The ragweed pollen season is slowly coming to an end!

Changeable weather conditions and rainfalls are expected for this weekend. These conditions will effectively wash out pollen and spores from the air resulting in a relief for pollen allergy sufferers.

The peak of the ragweed pollen season in eastern Austria has passed. Despite very high concentrations have been recorded during the past days, such burden is not expected anymore. The local ragweed populations and the pollen that reaches the country by long-distance transport will from now on only result in low to moderate burden. Only in the close vicinity to larger populations high burden still must be expected.

The flowering period of Mugwort, plantain and nettle has ended. There will be only low pollen concentrations for the remaining duration of this year’s pollen season.

The flowering period of most grass species has ended. Some species may rebloom, but the pollen concentrations will not rise above moderate burden. Common reed is flowering as well but also passed its peak pollination period. Nevertheless, moderate to high burden must be expected in close vicinity to larger reed belt areas.

The pollen season in western Austria is ending.

The current weather conditions and the above average temperatures in September still result in moderate to high burden caused by fungal spores.

What else: The pollen spectrum contains pollen from Mercurialis, hop, cypresses and the goosefoot family and Ivy in addition, which is of low allergological importance.
