The Aerobiological Network of Catalonia has issued a warning for 2026, predicting an exceptionally strong allergy season in Barcelona due to optimal weather conditions for plant growth.

Data from the Autonomous University of Barcelona shows that pollination levels in February already exceeded historical averages. While early cold delayed some species, recent mild temperatures and abundant water have led to a vigorous start for trees like the plane tree and oak.
Approximately two million people in Catalonia suffer from respiratory allergies. The Catalan Society of Allergy and Clinical Immunology reports that 25% of the population has rhinitis, and these figures are expected to rise significantly by 2050 due to the combined impact of climate change and pollution.
Pollution is not only affecting human health but also modifying pollen composition, making it more aggressive. Tools like the Planttes platform are becoming essential for citizens to track allergenic plants in urban areas and minimize their exposure during this challenging season.
