In spring, tree pollen is common. Birch is a major source in March and April. Oak, ash, and willow also release pollen then. This is one of the busiest pollen times of the year in The Netherlands.

In late spring and summer, grass pollen becomes important. Many grasses release pollen from May through July. This can include meadow grass and ryegrass. Warm, dry, and breezy days can carry the pollen farther.

In late summer and early autumn, weed pollen can still be in the air. Plants like mugwort and plantain release pollen then. This time is usually smaller than spring or grass season, but it can last into September.
