Updated: 2/11/2026

In March and May, oak and birch trees release pollen. It's like a yellow rain. This pollen season is stronger than the first one. Many trees are blooming.

In June and July, grasses release pollen. This season is shorter than the others. Hot weather helps the grasses grow and release more pollen.

In August and September, weeds like ragweed release pollen. This season is shorter too. By October, the pollen seasons are over, and the air is cleaner.
