In Cambridge, trees start producing pollen in late March. This means they release tiny particles into the air. It's usually birch and oak trees that do this.

In April, grasses start growing and producing pollen too. This adds to the amount of pollen in the air. People might notice it's getting worse.

By May, most trees and grasses are producing pollen. This is the peak of pollen season. The air is full of tiny particles making it hard to breathe.

By June, pollen levels start to decrease. Trees and grasses stop producing as much pollen. The air clears up, and it gets easier to breathe again.
