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

Updated: 3/14/2026

Tree pollen season starts in March and ends in May. Trees like oak, birch, and hazelnut release pollen into the air. This pollen floats in the air and can be seen on cars and clothes.

Grass pollen season is from May to July. Different types of grass release pollen, making it hard to breathe for some people. When it's hot and dry outside, more pollen is in the air.

Weed pollen season is from July to September. Weeds like ragweed and sagebrush release pollen. When the wind blows, pollen spreads everywhere, even inside homes and buildings.
