Situation and medium-term forecast

Low to moderate burden from hazel and alder pollen!
The readiness to flower is attained for hazel and alder in many places. The flower will start only under certain conditions such as temperatures above 5°C and dry conditions. The hazel and alder pollen season 2019 is characterized by a rather late start of the pollen season.

Up to now, only low hazel and alder pollen concentrations were recorded. The situation will change if the forecasted fair weather will arrive: The onset of the flower and first moderate hazel and alder pollen concentrations have to be expected, if ideal conditions (temperatures of about 10°C, sunshine) should be provided.
Relief still continues in the cooler regions of Austria.

Note: The immune system of a pollen allergy sufferer may be particularly sensitive at the start of the pollen season. Birch pollen allergy sufferers may be potentially concerned by the pollination of the “early bloomers” due to cross-reaction.

What else: The pollen spectrum contains also pollen from cypresses and yews.

Forecast from 13.02.2019
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.
