Pollen allergies happen when the body reacts to tiny particles from plants. In Umeå, Sweden, trees, grasses, and weeds release pollen into the air.
Birch trees release pollen in late April and early May. This is the most intense pollen season in Umeå. Airborne pollen counts are highest during this time.
Grasses and weeds release pollen in June and July. This pollen season is shorter but still causes symptoms. Airborne pollen counts are lower than in the spring.
Pollen levels vary from year to year, depending on weather conditions. Rain and wind can reduce pollen levels. Check daily pollen forecasts to plan your activities.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
