Forecast

The main ragweed flowering season is over, but high pollen levels are still possible!

It may rain in Burgenland on Monday night and Monday morning, which will temporarily reduce pollen levels. Following this rainfall, fungal spore counts may pick up again and cause high levels of exposure. The rest of the week is expected to remain cloudy to sunny but dry. In Burgenland, the pollen season is already well advanced, and most herbaceous allergenic plants, such as grasses, stinging nettles, plantains and amaranths, have finished pollinating. These are now usually only detectable in small quantities in the ambient air. Ragweed pollen concentrations are also showing a downward trend. However, as this introduced species is highly allergenic and even a few pollen grains per cubic metre of air can trigger symptoms, people with sensitivities should avoid areas with dense stands of ragweed.

Local stands of ragweed in Burgenland may continue to cause moderate levels of pollen exposure. As westerly to north-westerly winds are expected to prevail over the coming days, long-distance transport from southern and south-eastern Europe is unlikely for the time being. 

The fine weather is encouraging the flowering of annual mugwort and Kamchatka mugwort. Both species are late-flowering and occur in Burgenland both naturally and as cultivated plants. They may still cause symptoms locally. As mugwort and ragweed both belong to the Asteraceae family, cross-reactions are possible.

Following the increased release of fungal spores at the start of the week, levels will stabilise at a moderate level by the middle of the week. 

Pollen from hemp plants, impatiens and ivy are also present in the pollen spectrum. However, they pose only a low allergenic risk.
