Situation and medium-term forecast
A rainy Saturday provides a little bit of respite for pollen allergy sufferers!
On Saturday, rainfalls will arrive all over Austria. These will bring short-term relief for pollen and fungal spore allergy sufferers. The rest of this weekend and the start of the coming week will be sunny and dry. These conditions will be ideal for pollen and fungal spore release, therefore a rise in allergenic burden can be expected.
In the valleys and lowlands of Austria, the peak grass pollen season has passed, and their allergenic burden reaches low to moderate levels. At higher elevations, the flowering of the grasses is now in full swing resulting in moderate to high pollen concentrations on sunny days. Currently, yellow oat grass and Bermuda grass are in full bloom but also scattered flowering cock’s-foot grass, ryegrass, timothy and meadow-grass can be encountered. Grass pollen allergy sufferers should avoid flowering meadows and green spaces because here the local burden is higher. Dock and plantain are flowering and may cause additional allergenic burden in the vicinity of meadows.
Currently, pollen of members of the nettle and the goosefoot family are commonly present in the pollen spectrum but it is only of low allergenic relevance.
The flowering season of sweet chestnut is ending with low pollen concentrations. Its pollen may be of relevance to birch pollen allergy sufferers due to possible cross-reactions.
Besides the main aeroallergens, the following pollen types were registered in the pollen spectrum: cypresses, tree of heaven, lime tree, scorpionweed, and members of the bedstraw family.
The humid weather conditions promote fungal spore production and release. For this weekend moderate to high fungal spore burden can be expected.

Forecast from 09.07.2020
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.
