Pollen information for Lower Austria from 21 July 2025
Relief for pollen and spore allergy sufferers at the start of the week!
The heaviest precipitation is expected in Lower Austria on Monday. This will bring some relief for pollen and spore allergy sufferers. From Tuesday onwards, it will be mostly sunny. The spore count will quickly rise to a high level and grass pollen concentrations will mostly reach moderate levels.
Although the peak bloom of the widespread grasses is behind us, grasses continue to bloom in open fields, forests and at higher altitudes. Occasionally, grass pollen counts can be high locally, but the level is moderate across the board. Maize is now flowering in large parts of Lower Austria. The pollen of this sweet grass, which is used intensively in agriculture, is one of the largest in the plant kingdom and therefore usually only causes relevant concentrations in the ambient air in the immediate vicinity of the fields.
Especially on hot and dry days, plantain and dock dust intensively and thus cause additional pollution. Stinging nettles also bloom and their pollen can irritate sensitised people.
Flowering mugwort specimens are becoming increasingly common from the Enns to the March. Their numbers will continue to increase over the course of this week, so we are expecting the first allergy-relevant pollen concentrations in the ambient air. However, people who are sensitised to mugwort should already avoid typical locations with dense stands such as dry grassland, field edges or road verges.
Allergy sufferers can expect short-term relief at the beginning of the week during the precipitation. However, we expect the concentration of fungal spores to quickly rise again to a high level as soon as the rain has subsided. The grain harvest that is currently taking place may have an additional negative impact. This is because large quantities of fungal spores are released into the ambient air during this dusty affair. Allergy sufferers should avoid the area around these fields.
The pollen spectrum is currently stable. For this reason, the frequency of text forecasts will be reduced to once a week for the coming weeks. However, our team at polleninformation.at will continue to monitor the situation on an ongoing basis and will, of course, send out appropriate information should there be any changes to the expected pollen count. The monitoring centres operated by us and our colleagues will remain active in order to keep all the services provided, such as the hourly allergy risk, up to date.
Other types of pollen in the ambient air: umbellifers, goosefoot and buttercups as well as cloves and cypresses. These are of minor allergological importance.
