In late spring, grass pollen becomes important. This season usually runs from May into July. Many common grasses release pollen then, such as ryegrass and meadow grass. Warm, dry, and windy days can carry the pollen farther across fields and gardens.

In summer, weed pollen can be active. It often appears from June through September, with some plants lasting into early autumn. Nettles and plantains release pollen during this time. Mugwort may also send pollen into the air in later summer.

In autumn and winter, pollen levels are usually lower. Most trees and grasses have finished releasing pollen by then. A few plants may still produce small amounts on mild days. In Bourne, this is the quietest time for pollen in the air.
