During this time, trees like oak, birch, and hazel release tiny particles into the air. These particles are light and can travel far. They can even stick to clothes and skin.
The tree pollen season ends in April. Then, the grass pollen season starts. Grasses like wheat, barley, and oats release their pollen in May and June. This pollen is light too and can travel far.
The grass pollen season ends in July. Then, the air is cleaner until the next year's tree pollen season starts. Trogir's pollen seasons can be tricky, but people can be prepared.
