In spring, birch trees release a lot of pollen. This is usually in April and May. Willow and oak trees also add pollen then. Many parks and streets in Naaldwijk can have these trees, so spring is often a busy time for pollen in the air.

In early summer, grasses become the main pollen source. This usually starts in May and lasts into July. Meadow grasses, lawn grass, and other wild grasses release pollen on warm, dry days. In and around Naaldwijk, open fields can make this season very active.

In late summer and autumn, weeds can still release pollen. Mugwort is one common plant, and nettle can add some too. This often happens from July through September. By October, most pollen in Naaldwijk has usually gone down a lot.
