Cold weather conditions largely prevent pollination!

During the first few days of the new year, temperatures rarely exceed 5°C, which means that pollen is unlikely to be present in the air.

As usual, the purple alder started flowering over the Christmas holidays and can continue to release pollen if the weather conditions are right. However, as this alder species is only occasionally planted, allergic reactions are only to be expected in its immediate vicinity.

Due to the cold spell over the past few days, hazel and alder are expected to be ready to flower between the middle and end of January. In thermally favorable locations, however, localized pollen counts may occur earlier.
The expected start of the hazel and alder pollen season is determined by forecasting models based on temperature forecasts, the accuracy of which increases as the season approaches.

The Austrian Pollen Information team wishes you a good start to the new year!
