The first pollen season starts in February with hazel and alder trees releasing pollen. This is followed by birch trees in March and April.

In May and June, grasses and weeds release pollen, causing high levels in the air. This is usually the worst time for people with pollen allergies.

The pollen season ends in August, but some people may still react to weeds and late-blooming flowers. It's essential to check pollen forecasts to plan daily activities.
