In April and May, grass pollen fills the air. This makes lots of people sniffle and sneeze outside. Trees like oak, ash, and birch produce lots of pollen too.
Summer isn't over yet, but weed pollen starts rising in July. Nettles and docks are common weeds that produce pollen. It can still make people feel uncomfortable.
By September, pollen counts start decreasing. It's still around, but not as much as in spring and summer. Winter months usually have very low pollen counts.
