Pollen allergies affect many people in Bilbao. Trees, grasses, and weeds release pollen into the air. This causes symptoms like sneezing, runny nose, and itchy eyes.
In Bilbao, pollen seasons start in January with trees like olive and birch. During February and March, holm oak and oak trees release pollen. In April and May, grasses pollinate.
Summer brings weeds like plantain and sorrel, causing pollen levels to rise. September and October are also peak pollen months. November marks the end of pollen season.
Knowing the pollen season helps people with allergies plan ahead. They can stay indoors during peak hours, use air purifiers, and avoid activities that stir up pollen.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
