In spring, grass pollen becomes very common. Grasses bloom from April to July, with the strongest season in May and June. Meadows, parks, and roadside grasses all send out pollen. Warm days and dry weather can make the pollen travel farther.

In summer, weed pollen takes over. Plants like mugwort and plantain release pollen from July into September. Some other wild plants also add to the air. This season is often strongest in late summer, when many weeds grow along fields and paths.

In autumn, pollen levels usually get lower in Celje. Most trees and grasses have already finished. A few late weeds may still release some pollen in September and October. Cooler, wetter weather usually means less pollen in the air.
