Birch trees are the worst offenders. They release a lot of pollen into the air. This lasts until mid-May. Then, the birch pollen count goes down.

In May, grasses start releasing their pollen. This continues until June. It's not as bad as the birch pollen, but still a problem. Some days are worse than others.

The pollen count usually goes down in July. This means air quality improves. People who suffer from pollen can finally feel better. It's a welcome relief after a few months of discomfort.
