In spring, tree pollen is at its highest. Birch, oak, and pine can spread a lot of pollen. Grasses also begin later in the season. Wind carries this pollen across parks, streets, and hills around the town.

In early summer, grass pollen becomes important. Many meadows and lawns around Český Krumlov release it. Timothy, ryegrass, and other common grasses are active then. Warm, dry days can keep pollen moving for a long time.

In late summer and early fall, weed pollen is common. Mugwort and ragweed may release pollen then. Some wild plants along roadsides and fields add more. By late fall, cooler weather lowers pollen levels, and most plants stop for the year.
