Situation and medium-term forecast
Reduced allergenic burden!
Unusual low temperatures and rain-/snowfall are expected throughout the next days, causing unfavourable conditions for pollination. Therefore, pollen allergy sufferers may experience a reduced level of allergenic burden during the first half of this week. As soon as the weather conditions are changing, a quick increase of allergenic burden must be expected.
Especially birch pollen allergy sufferers must expect moderate to high levels of allergenic burden because most trees already reached readiness to flower and are waiting for the right moment to start flowering.
Due to cross-reaction, the flowering of hornbeam may already causes burden for pollen allergy sufferers who are sensitized to birch pollen.
In addition to that, ash pollen is causing allergenic burden as well. Even though most trees, in the eastern parts of the country already passed the peak flowering period, moderate to high levels of allergenic symptoms still must be expected.
What else: The pollen spectrum contains also pollen from acer, elm, poplar, willow, rose family, cypresses and yews.

Forecast from 27.03.2023
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.
