Situation and medium-term forecast

Unstable weather conditions are causing varying allergenic burden!

While sunny weather conditions dominate in the western parts of the country from Monday, snow and rainfall are prevailing in the eastern parts. But until the conditions will change until Wednesday, where sunshine is expected throughout the country before it starts to rain or snowing again. Due to these conditions and temperatures that will not rise above 5 °C no extensive pollination is expected in Austria.

Note: Allergenic burden caused by hazel or alder pollen still must be expected at climatically favored areas or in foehn regions.

The current climatic conditions slow down the development of hazel and alder catkins a little. But since hazel is already well developed low allergenic burden still must be expected in certain areas of the country. Alder still needs some time until their catkins reach readiness to flower.

The Spaeth’s alder has passed its pollination period and will cause burden only in close vicinity of the plants.

The forecasted start date of the hazel and alder pollen season is calculated based on forecast models. Due to the uncertainty of long-term temperature forecasts, the actual flowering start of hazel and alder can still vary. The forecasts become more accurate as the season approaches.

What else: The pollen spectrum contains pollen of cypresses and yews.

Forecast from 24.01.2022
Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
