Forecast

Rain will bring some temporary relief!

Thursday and Friday will bring overcast, wet weather to Vienna, with repeated showers, a brisk westerly to north-westerly wind and temperatures of just 17 to 21 degrees. From Saturday onwards, the sun will increasingly break through, and with maximum temperatures of 20 to 24 degrees, pollen levels will also rise rapidly again. Ragweed remains the main allergen in Vienna.

Ragweed pollen is highly allergenic and can trigger significant allergic reactions even in the smallest quantities. As winds from the north and west are expected to prevail over the coming days, long-distance transport from eastern and south-eastern Europe is not anticipated for the time being. Nevertheless, local Viennese populations will cause moderate to high pollen levels on dry, sunny days.

Common mugwort has also largely finished flowering in Vienna; significant pollen levels are limited to the immediate vicinity of large stands. However, as annual mugwort and Kamchatka mugwort are beginning to flower sporadically, a second peak in pollen levels is possible later this week. Cross-reactions with ragweed are possible.

People with grass pollen allergies may experience symptoms again as reed flowering begins. As the wind is predominantly blowing from the north or west, long-distance transport of reed pollen from Lake Neusiedl to Vienna is not expected for the time being. Significant pollen levels are therefore only likely from locally planted ornamental grasses.

Fungal spore levels are slowly falling to moderate levels. Those affected should, where possible, limit time spent outdoors immediately after rain.

Pollen from stinging nettles, amaranths and plantains continues to be present in the pollen spectrum. However, these pose only a low allergenic risk.
