Mid- and long-term forecast for Vienna

This forecast gives you an overview for a longer time period so that you can improve your planning.

The cold front continues to prevent the release of pollen!

As forecasted, purple alder catkins began to flower in Vienna during Christmas week. The first catkins are already fading (see image). With the continuation of the cold front and winter conditions with temperatures around freezing, pollen release is unlikely in the coming days.
The purple alder (Alnus x spaethii) is a hybrid of Japanese and Caucasian alder that only occurs in areas where it is planted. It is so rare in Vienna that it does not cause any measurable pollen dispersal. We observe and report on its flowering with the help of phenology.

The common hazel, the Turkish hazel and the native alder species are still dormant and have not yet reached flowering stage.

The Pollenservice Vienna of the MedUni Vienna measures 365 days a year and observes the development of the vegetation continuously.
