In spring, pollen is common from April to May. Birch, oak, plane tree, and pine can all add pollen to the air. Grasses also start growing and sending out pollen. This is one of the busiest pollen times.

In early summer, grass pollen is still strong. Many meadows and field edges around Zalău can release it. Ryegrass and other wild grasses are common sources. Some trees, like lime, may also bloom and add more pollen.

In late summer and early autumn, weed pollen becomes more important. Plants such as mugwort can release pollen in this time. The air usually has less tree pollen now. By late autumn and winter, pollen levels drop much lower.
