In March and April, birch trees start pollinating. This is the busiest time for pollen. Many trees and grasses release pollen, making the count very high. Stay indoors on windy days.
In May and June, grasses take over. They release a lot of pollen, making the count high again. Watch out for sunny days, when pollen counts are highest.
By July, pollen seasons are almost over. Only a few trees and grasses are still releasing pollen. The count is low, and the air is cleaner. Outdoor activities are more fun again!
