Situation and medium-term forecast

Fair-weather + birch bloom = bad times for pollen allergy sufferers!

After the weekend the flowering of birch is now in full swing in the lowlands and valleys all over Austria. The fair-weather boosts pollen release and this week pollen allergy sufferers can expect the peak in birch pollen concentrations and allergenic burden.

Hornbeam is also flowering. It is part of the birch family and its pollen can intensify the allergenic burden for pollen allergy sufferers sensitized to alder, birch and hazel.

In the east of Austria, the flowering of the ash trees is now past its peak pollination but can still lead to high allergenic burden. In the west and moderate altitudes of the Alps the ash bloom has started with a few weeks of delay. Here the ash trees have retained much of their flowering potential and allergenic burden. In alpine basins high pollen concentrations and allergenic burden are expected for the duration of this week.

The pollen of the following plants was also registered in the Austrian pollen spectrum: elm, ginkgo, maple, oak, poplar, willow, cypresses and yews.

Useful hints: Pollen allergy sufferers should refrain from strenuous work outdoors in the coming days.

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 in addition from you.

Forecast from 06.04.2020
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.
