Eyes starting to itch?
Tree pollen starts hay fever season

Nose running? Eyes itching? The fresh hay fever season is starting to pick up, first in the air is tree pollen.

Each year, the annual pollen season gets started with tree pollen in the air from March, followed by grass and weeds later in the year.

Right new, yew and alder are flying strong. From May, grass pollen starts to rise with weed pollen starting in June.

Stay prepared for whatever this hay fever brings with pollen forecasts in the app.
