Jena, 21.04.2026 – Allergy sufferers in Jena and the surrounding area must show strong nerves this Tuesday. A high concentration of birch and ash pollen is currently causing a noticeable burden for hay fever patients.
- Date: Tuesday, 21.04.2026
- Warning level: High
- Dominant pollen types: Birch and ash
- Area: Entire city area of Jena
Spring brings high pollen concentration
The current weather conditions in April are massively favoring the pollen count in the Jena city area. Particularly the highly allergenic birch as well as ash are currently dominating the air. Corresponding temperatures and persistent wind ensure a continuous, rapid, and far-reaching distribution of the fine floral dust, which triggers typical hay fever symptoms such as sneezing, watery eyes, or respiratory complaints in many people.
Background: Allergy burden in the City of Light
Due to its striking geographical basin location in the Saaletal, Jena is repeatedly and particularly affected by pollen counts. On warm and dry spring days, air circulation can be restricted by the adjacent Kernberge, causing the pollen load to literally accumulate in the lower air layers of the city. The dense and diverse tree population in the Saaleauen, in the Paradiespark, and in the urban green spaces ensures local peak values during the main flowering period.
Prevention tips for allergy sufferers:
- Proper ventilation: In heavily populated urban areas, the pollen load is usually highest in the evening. Ideally, ventilate your living spaces in the early morning hours between 6:00 and 8:00 AM.
- Everyday hygiene: Wash your hair before going to bed to remove adhering pollen. Worn street clothes should also not be left in the bedroom.
- Eye protection: Wearing close-fitting sunglasses when outdoors effectively protects the eyes from direct contact with the airborne allergens.
