Overview
- Hazel and alder pollen are already in the air across many regions, with the DWD cautioning that mild, dry and windy conditions can send alder counts up quickly.
- Forecasts indicate high early‑week exposure in parts of the country—especially the southwest—during an unusually warm, largely dry first week of March.
- Regional timing differs after a cold winter delayed the start in parts of Saxony‑Anhalt, but experts stress the overall burden is shifted rather than reduced.
- Ash is expected next and birch is set to peak from April, a major trigger for many patients according to pollen services and clinicians.
- Health authorities urge early diagnosis and symptom control with antihistamines and corticosteroid nasal sprays, consideration of specific immunotherapy, and regular use of DWD and Pollenstiftung apps plus ventilation timing to manage daily risk.
