In April, grasses start releasing pollen. This adds to the amount of pollen in the air. People with allergies might start to feel symptoms like sneezing and itchy eyes.

In May, pollen counts are usually the highest. This is because many trees and grasses are releasing pollen at the same time. It's a good idea to stay indoors on windy days.

By June, pollen counts start to go down. Fewer trees and grasses are releasing pollen. The air starts to feel cleaner, and people with allergies might start to feel better.
