In late spring, grasses start to release their pollen. This is usually in May and June. It's a big problem for people who react to grass pollen.

The summer months are quieter for pollen. But in late summer, weeds like nettle and sorrel release their pollen. This is usually in July and August.

In autumn, pollen levels drop. The air is cleaner, and people who react to pollen can breathe easier again. This is usually from September to November.
