Banja Luka, Bosnia and Herzegovina has a moderate continental climate with four seasons. Spring and fall are generally mild, while winter is cold and summer is warm.
Pollen season in Banja Luka typically begins in late March with tree pollen, followed by grass pollen in May and weed pollen in late summer. Levels can be high, especially in rural areas.
The city's climate and geography can contribute to high pollen counts. Banja Luka is situated in a valley, which can trap pollen and other allergens, leading to potentially longer and more intense pollen seasons.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
