Grass pollen levels remain high!

It remains hot and dry. Only at the weekend may there be brief showers in Vienna. Depending on how heavy these are, allergy sufferers may experience some relief. The grass pollen season remains the main cause of the current high levels. At the moment, brome grass, false oat-grass, false barley, annual meadow grass, vernal grass, cock's foot grass, ryegrass and foxtail grass, are responsible for the high pollen concentrations being recorded.

In meadow areas, additional exposure from sorrel and plantain is also possible.

In the Vienna countryside, rye may also be starting to flower in arable fields, causing additional pollution near the fields. However, as rye pollen is significantly larger and heavier than the pollen of naturally occurring grasses, it cannot be carried as far by the wind.

Please note: Thunderstorms may occur over the weekend. This weather phenomenon can cause pollen grains to burst, releasing allergens into the air. This can lead to sudden spikes in pollen levels and the associated symptoms. You should therefore check the severe weather forecast to find out in good time whether so-called thunderstorm asthma is likely.

Linden blossom is in full swing and will continue to result in clearly measurable pollen concentrations in the air over the coming days – even though this plant is adapted to insect pollination and does not normally release much pollen into the air. The scent of the blossoms can also irritate the airways of sensitive individuals.

Our air samples are also containing increasing amounts of fungal spores, which can cause symptoms in people with allergies.
