Situation and medium-term forecast

This weekend, winds from the east will deliver high amounts of ragweed pollen!

In the eastern and southern regions of Austria, ragweed ceases its flowering. In Burgenland, Lower Austria, Vienna, and parts of Carinthia, Styria, and Upper Austria commonly low to moderate pollen concentrations have to be expected for the coming days. In close vicinity to large ragweed populations higher allergenic burden has to be expected. Due to winds coming from the east the local allergenic burden can increase up to high levels in the east of Austria. Here you can see the ragweed reports from 2020 and you can report your findings as well: www.ragweedfinder.at

Goldenrod is still flowering. This plant is insect-pollinated and does not cause noticeable widespread pollination but might be of importance for sensitive persons with sensitization to composite plants (like mugwort and ragweed) in direct contact with it.

In the vicinity of wetlands with reed belts, higher grass pollen concentrations have to be expected. Reed continues flowering.

The pollen spectrum contains pollen from ivy, plantain, the goosefoot, the nettle, and the parsley family, which is of low allergological importance.

In the lowlands, a moderate fungal spores load is to be expected for this weekend. The burden from fungal spores decreases with sea level.
