Annual Overview

In Cardiff, pollen seasons start in March. This is when trees like oak and birch start releasing pollen. It's a lot of tiny yellow dust.

In April, grasses start growing and releasing pollen too. This is the worst time for people who don't like pollen. There's so much of it in the air.

In May, some trees like pine and hazel release even more pollen. It's not as bad as April, but it's still a lot. Summer is coming, and pollen will slow down soon.

By July, pollen seasons are mostly over. There might be a few days with high pollen counts, but it's usually okay. People can enjoy being outside again without worrying too much about pollen.
