In Sittard, Netherlands, pollen seasons happen every year. There are three main pollen seasons: tree pollen, grass pollen, and weed pollen.

Updated: 3/21/2026

Tree pollen season starts in March and ends in May. During this time, trees like oak, birch, and hazel release pollen into the air. This makes the air yellow and sticky.

Grass pollen season is from May to July. Grasses like wheat, oats, and barley release pollen, making it hard to breathe for some people. This is the worst pollen season in Sittard.

Weed pollen season is from July to September. Weeds like nettle, sorrel, and dock release pollen, causing problems for some people. This season is not as bad as the grass pollen season.
