Birch and ash pollen cause problems!
The past few days have been characterized by low temperatures and precipitation, which has significantly slowed down the pollen count.
The elm pollen count has now ended and the hazel season is also over. Alder pollen is only present in small quantities.
Hornbeam pollen, on the other hand, is currently flying strongly and poplar pollen is also still present. As expected, the ash tree has begun its pollen flight. In addition, the birch pollen count is expected to start in the coming days - the first birch pollen has already been observed. Although no measurable quantities have been registered yet, birch pollen allergy sufferers are already reporting severe symptoms.
From tomorrow, temperatures in Graz will rise again to over 16 °C and no precipitation is forecast. The weather will remain stable and dry until the weekend, which will significantly increase the pollen count. The coming days will be correspondingly challenging for pollen allergy sufferers.
