Forecast

Weather continues to allow little airborne pollen!

Fog and clouds are likely to persist over Vienna this week too. The number of hours of sunshine will only increase again towards the weekend, which will also increase the likelihood of more intense pollen count complaints.

On days with temperatures above 5 °C and dry conditions, more and more complaints due to hazel pollen in the air are to be expected. In addition, there are recent relevant concentrations of purple alder pollen in the ambient air.

The native alders still need some time and sunshine before they are ready to flower. The tree and shrub hazels, on the other hand, are already further advanced in their development and are already causing problems.

Note: The immune system of pollen allergy sufferers can react particularly sensitively at the start of the pollen season. Birch pollen allergy sufferers could also potentially be affected by the pollen count of "early bloomers" due to cross-reaction.

In addition to the pollen types mentioned above, the following are also represented in the pollen spectrum: Cypress plants. However, they only have a very low potential to cause allergic reactions.

The weather also has an impact on the flowering readiness model. From a current perspective, the data tends to indicate that flowering readiness will be reached in mid-February.
