Spring brings many more pollen sources. Birch is common in April and May. Then hornbeam, oak, and pine add more pollen. Grasses begin later in spring, and they stay important through early summer.

Summer is mainly the time for grass pollen. Many kinds of meadow grasses release pollen from May into July. Rye can also add pollen in early summer. In warm, dry weather, pollen from grasses often stays in the air longer.

Late summer and early autumn bring another group of plants. Mugwort usually releases pollen from July into September. Nettle can also be present in summer. By October, pollen levels usually drop as the days get cooler.
