Friendly weather at Easter and high loads from the birch!

After a cool and rainy Holy Week, the weather improves for Easter. The weather remains bright, it gets drier and the maximum daily temperatures rise to over 20 °C. These ideal conditions for the pollen count benefit the birchwhich is in the starting blocks, will benefit from these ideal pollen release conditions. From the Waldviertel to the Schneeberg, birch pollen allergy sufferers can expect very high levels this weekend. You should therefore plan your outdoor activities very carefully, take precautions to avoid allergens and remember to take suitable emergency medication with you.

The birch trees in Lower Austria have an above-average number of catkins this year. Before the cold snap, the first specimens were ready to flower, but the cold and rain prevented them from releasing pollen. The birch trees in the Waldviertel, Weinviertel, Mostviertel and Industrieviertel will begin to bloom almost simultaneously in the fine weather phase that will now follow, resulting in very high concentrations of birch pollen in the surrounding air.

Another birch plant is the hornbeam which is also just beginning to flower. As birch, alder, hornbeam and hazel are closely related, cross-reactions can occur in sensitised people.

In Lower Austria, the flowering of ash, poplar and willow continue to progress. They will contribute to the pollen load in addition to birch.

The forsythia is related to the ash tree. The catkins are the inflorescences of the willow. They can cause cross-reactions in sensitised people. It is therefore advisable to avoid using decorative forsythia and pussy willow branches as indoor Easter decorations.

In addition to the pollen types already mentioned maple, yew and cypress plants are represented in the pollen spectrum. However, they only have a very low potential for allergic reactions.

Despite the expected stress, the Austrian Pollen Information team wishes everyone a happy Easter and relaxing holidays.
