Achoo! - Hazel and Alder Pollen Already Flying in Bavaria - Bavaria's Hay Fever Season Starts Early as Climate Change Alters Pollen Patterns

Bavaria is facing an early start to the hay fever season as unseasonably mild February temperatures trigger hazel and alder pollen release. Around 1.4 million residents suffer from allergies, with symptoms like itchy eyes, runny noses, and sneezing already appearing weeks ahead of usual schedules due to climate change. Experts link the shift to rising temperatures caused by climate change.

Over the past decade, hazelnut and alder pollen seasons in Bavaria have begun significantly earlier than in previous decades. Peak pollen counts now arrive one to three weeks ahead of time, while overall pollen loads have grown heavier due to climate change. This change particularly affects allergy sufferers in late winter and early spring, when symptoms would normally remain mild.

The state's electronic Pollen Information Network (ePIN) tracks these shifts with eight monitoring stations, updating pollen counts every three hours. A free ePIN app also includes a pollen diary feature, helping users identify their triggers and adjust medication or behaviour accordingly.

Climate change appears to be lengthening and intensifying pollen seasons, though researchers stress that more data is needed to confirm long-term trends. For now, sufferers are advised to consult doctors and take prescribed medication if symptoms worsen.

With hazel and alder pollen already circulating, allergy sufferers in Bavaria must prepare for a longer and more intense season due to climate change. The ePIN system and its app provide real-time updates, while medical advice remains essential for managing symptoms. Experts continue monitoring how climate shifts may further alter pollen patterns in the coming years.
