In late spring and early summer, grass plants release pollen. This usually happens in May and June. Grass pollen can spread across fields, lawns, and roadsides. Warm and windy days can carry it farther. Many outdoor places have grass pollen then.

In summer, some weeds begin to bloom and make pollen. This can happen from July into August. Plants like mugwort and nettle may release pollen during this time. They often grow along paths, fields, and open ground. Their pollen season is usually shorter.

In late summer and early autumn, weed pollen can still be in the air. This time often continues into September. Some plants finish flowering, but a few keep releasing pollen. After that, pollen levels usually drop as the weather turns colder.
