Grass pollen today
Grass pollen is not high anywhere we track today. Season runs May to August, peaking in June and July.
Grass pollen affects more people in Europe than any other allergen. The season is long — usually six to eight weeks of high counts — and it peaks on warm, dry, breezy afternoons. Unlike tree pollen, which arrives in a short intense burst, grass drags on through most of the summer.

Common questions
When is grass pollen season?
Grass pollen runs from May into August across most of Europe, peaking in June and July. It starts earlier in southern Europe and later in Scandinavia.
What time of day is grass pollen worst?
Counts typically climb through the afternoon and into the early evening, when warm air that lifted pollen during the day begins to cool and bring it back down.
Why does grass pollen affect so many people?
The grasses that trigger hay fever — timothy, ryegrass, cocksfoot and others — are widespread across parks, verges, farmland and lawns, so exposure is hard to avoid in any European city.
