In Ixelles-Elsene, the first pollen season often starts in late winter and early spring. Hazel and alder trees release pollen first. Soon after, birch trees add more pollen to the air. This time can begin in February and grow stronger in March and April.

In spring, grass pollen becomes very common. It usually appears from April to July. Many lawns, parks, and meadows send out grass pollen. This season is often busy in May and June, when warm weather helps grasses grow and flower.

In early summer, some trees are still releasing pollen. Oak, pine, and plane trees can add pollen in May and June. Their pollen may drift through streets, gardens, and green spaces. This period often overlaps with the end of the grass season.

In late summer and early autumn, weed pollen can appear. Mugwort and nettle are two common plants that release pollen then. This season often runs from July to September. It is usually weaker than spring, but it can still be present on warm, dry days.
