Situation and medium-term forecast
High allergenic burden during the Easter holidays! Rainfalls and relief are coming next week!
The pre-summer high temperatures and sunny weather have promoted pollination during the Easter holidays.
The birches are currently at their pollen release peak. In all nine Austrian states, high birch pollen concentrations have been registered. This year the number of catkins per tree is above average. In combination with the Fair-weather conditions during the birch bloom, the allergenic burden for birch pollen allergy sufferers will remain high.
For the at the moment flowering hornbeams the amount of released pollen will also be above average this season. Its pollen can be cross-reactive to pollen allergy sufferers sensitized to alder, birch or hazel and may cause symptoms.
The bloom of the ash trees has started several weeks ago. Its peak in pollen release has already past but they still may cause moderate to high allergenic burden. The trend of constant high pollen concentrations and symptom load will continue until the start of next week.
Beginning on Monday in the west of Austria, rainfalls will bring relief to pollen allergy sufferers from Vorarlberg to the northern pre-alpine forelands. Carinthia, Styria and the southern part of the Burgenland will have to wait for another day until rainfalls and relief arrive.
The plane tree has started to blossom as well in parks and avenues. Pollen allergy sufferers sensitized to this plant should avoid proximity to this tree at the moment.
The pollen of the following plants is currently airborne in Austria: elm, ginkgo, maple, members of the nettle family, oak, poplar, willow, cypresses and yews.
Useful hints: Pollen allergy sufferers should reduce their outdoor-time and should not plan any strenuous work for the Easter holidays.
The face masks which are at the moment obligatory for shopping groceries are also very useful for pollen allergy sufferers. The face masks offer protection against pollen and keep it from entering the respiratory system.
Protect your conjunctiva mechanically and very simple with sunglasses: part of the pollen is kept from your eyes and you thus protect your already irritated mucous membranes of your eyes, which are more sensitive to light than usual during an allergic reaction. A hat with a broad brim keeps pollen also from you.

Forecast from 09.04.2020
Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
