In early spring, from March to April, birch trees begin to bloom in Visby. Their pollen spreads in the air when the weather gets warmer. Alder and hazel may also release pollen around this time, especially on mild days.

In late spring, from April to June, grass pollen becomes common. Many types of grass release pollen in fields, lawns, and open places. Toward the end of spring, birch pollen can still be present, but grass often becomes the main pollen in the air.

In summer, from June to August, grass pollen can still be around. In some years, weeds also start to release pollen later in summer. Plants like mugwort and plantain may add more pollen during warm, dry days in Visby.

In late summer and early autumn, from August to September, weed pollen is often more noticeable. Mugwort is one of the main plants at this time. By autumn, pollen usually drops as many plants stop flowering and the weather turns cooler.
