Copenhagen, Denmark has a temperate climate with cold winters and mild summers. Spring and fall are the main pollen seasons.
Updated: 2/11/2026
In spring, tree pollen is prevalent, especially from birch, alder, and hazel. Allergy symptoms may include sneezing, runny nose, and itchy eyes.
During fall, weed pollen is more common, with ragweed being a major culprit. Symptoms can persist, but rain and wind can affect pollen counts. Climate change may prolong pollen seasons and increase pollen concentration.
