Forecast

The Vienna City Marathon is taking place this weekend!

Due to the change in the weather forecast for the weekend, which will bring a drop in temperature as well as occasional precipitation, we continue to assume that the pollen count and the associated adverse effects for allergy sufferers will be limited during the Vienna City Marathon.

The next update will be on April 4th!

Fluctuating exposure to birch and ash pollen!

The sunshine will dominate the weather until Friday and intensive pollen counts are to be expected with pleasant temperatures. At the weekend, the expected precipitation and the drop in temperature may provide short-term relief.

In addition to ash trees, which can continue to cause moderate to high levels of stress in people with sensitization to olive trees, the birch blossom is already causing high concentrations of pollen in the air and thus also intense allergic stress.
The flowering of hornbeam, which also belongs to the birch family, can further increase allergic stress in some people affected by cross-reactions.

With the next improvement in the weather, the first plane trees may begin to blossom. This tree is often planted in cities as an avenue tree and can cause very high pollen concentrations there, which can lead to considerable allergic symptoms.

Other types of pollen in the ambient air: maple, yew, rose, willow and cypress. These are of minor allergological importance.
