Situation and medium-term forecast
Weed pollen from mugwort increases in importance!
The main aeroallergen within the forecasted period will be weed pollen from mugwort. Mugwort already started flowering in the end of July. However, the main burden and the highest mugwort pollen concentrations are expected for this weekend throughout the country, even though mugwort is more frequent and thus intense in pollination in the East of Austria.
Mugwort pollen allergy sufferers could evade into higher altitudes. Hardly any burden is expected above a sea level of 1200 meters.
The start of the ragweed pollen season is expected for mid-August as well. Ragweed pollen will play a major role in the concerned regions of Austria, especially in Burgenland, Vienna, Lower Austria, Styria, parts of Upper Austria and Carinthia. A higher burden prevails in proximity to flowering ragweed, however the distribution varies.
Remark: A burden may occur on occasion in other regions of Austria as well or might be increased in the concerned regions of Austria due to long distant transport of ragweed pollen and to the more progressed flower of ragweed in the East and South of Europe. The West of Austria is still a recommended region for ragweed pollen allergy sufferers.

The grass pollen season is fading in the lowlands with a low burden. Furthermore, the grass pollen season is fading at higher altitudes as well and will only reach moderate concentrations there.
Dock and plantain are still causing additional burden.
Fungal spores occur in high concentrations in the air in the lowlands. The burden from fungal spores decreases at higher altitudes.
What else: The pollen spectrum contains pollen of nettle, hop and the goosefoot family.
