Situation and medium-term forecast for Vienna

Pollen information for Vienna from 19 March 2026

Increasing ash pollen count!

The weather forecast for the coming days promises slightly more hours of sunshine than in the first half of the week, but also an increased tendency for showers. If the precipitation is more intense, it is likely that pollen will be washed out of the air, thus reducing the symptoms. If the sun prevails for a little longer, intense pollen counts cannot be ruled out.

Pollen from early bloomers hazel and alder are only rarely registered in the pollen spectrum and therefore only cause very localised exposure. Most trees and shrubs have already shed their catkins and are therefore no longer a source of exposure for allergy sufferers.

The ash tree on the other hand, causes moderate to high levels of exposure in people who are sensitised to the pollen of olive trees.

Allergy sufferers who react to the pollen of this plant family should also refrain from bringing flowering forsythia branches into the living space for decorative purposes in order to keep it as pollen-free as possible.

The same applies to the palm catkins that can currently be seen in many places. These are the flowers of the sal willow . Although their pollen is only classed as moderately allergenic, allergy sufferers are advised not to place these branches in living spaces in order to avoid additional exposure.

The birch blossom is getting closer and closer. The first catkins may already be releasing pollen in thermally favoured locations such as sheltered courtyards or in very sun-exposed areas. However, it will still take some time before flowering begins across the board.

In addition to the pollen types mentioned, maple, yew, poplar and elm are also currently in flower,elmand cypress plants are also represented in the pollen spectrum. However, they only have a very low allergenic potential.
