Situation and medium-term forecast
The ragweed pollen season fades, mainly moderate pollen loads in the East!
The ragweed pollen season slowly fades, and the pollen concentrations are decreasing. However, a moderate burden from ragweed still has to be expected due to the local second flowering and long-range transport events from other European countries. Especially in the concerned regions of Austria, in Burgenland, Vienna, Lower Austria, Styria and parts of Upper Austria and Carinthia a noticeable burden is likely.
Remark: The burden may vary daily and in the course of a day – please consult the daily pollen load and our hourly forecasts such as the allergy risk! Please pay special attention to a possible burden during the night.
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 mugwort pollen season has overcome. Only single pollen grains are in the air, which do not exceed the sensitivity threshold.
The grass pollen season has overcome as well after the late flower of the reeds.
Dock and plantain flower and may burden in addition.
Golden rod is flowering. This plant is insect pollinated and does not cause a noticeable widespread pollination, but might be of importance for sensitive persons with sensitization to composite plants (such as mugwort and ragweed) in direct contact. Canada golden rod is a neophyte of importance in Austria and is used as ornamental plant in bouquets.
What else: The pollen spectrum contains pollen from ivy, the nettle and the goosefoot family in addition, which is of a low allergological importance.
The burden from fungal spores increased to high values again due to the late summer weather situation. Fungal spores occur in up to high concentrations in the air in the lowlands. The burden from fungal spores decreases with the sea level.
