Forecast

Pollen and fungal spores fly in the sunshine!

The weather forecast promises sunshine in the capital. For pollen and fungal spore allergy sufferers, this means days with moderate or high exposure.

Ragweed, which originates from North America, is in bloom in and around Vienna. Exposure to the local population can be increased by long-distance pollen transport when there are wind currents from the east. People who are sensitised to ragweed must therefore be prepared for moderate to high levels of exposure.
If you discover ragweed populations during outdoor activities, you are welcome to report them via the citizen science platform "Ragweed Finder". Reports can be made either via the website ragweedfinder.at or via app (for Android and iOS). They are checked by experts from the "Ragweed Finder" team, displayed graphically on the ragweed map and forwarded to the relevant authorities in the federal states at regular intervals. They can then use the reports to take further action.

Mugwort continues to flower until the end of September. Its first peak is already behind us. We expect only low pollen concentrations of this field weed in the coming days. Sensitised people should avoid dense populations of this composite plant, which can be found in areas heavily influenced by humans, such as field, path and roadside verges, as high levels of exposure can still occur here.

In the Vienna Woods, on green spaces or along roadsides in Vienna, some grass species continue to flower. One example of this is dog's tooth grass. Only low concentrations of grass pollen were recorded at our measuring station.

Plantain and stinging nettle dust and can cause additional pollution.

In Vienna, moderate to high concentrations of fungal spores will be reached in the coming days. At higher altitudes and above the tree line, the levels of fungal spores are noticeably lower.

Other types of pollen detected in the ambient air are bindweed, hemp, hops, umbellifers, goosefoot, cloves and cypresses. These are of minor allergological significance.
