In spring, tree pollen stays strong. Birch is one of the main sources, and oak and plane trees can add more. Grass pollen also begins later in spring. It often rises as lawns, fields, and meadows grow thicker and greener.

In early and mid-summer, grass pollen is often at its highest. Many common grasses release lots of pollen then. This includes meadow grass and ryegrass. Warm, dry days can make the pollen spread more easily through the air around town.

In late summer and early autumn, weed pollen becomes more important. Plants like mugwort and ragweed can release pollen during this time. Their season usually ends as the weather turns cooler. By late autumn and winter, pollen levels drop much lower.
