Forecasts on this page are updated daily and based on the CAMS European air quality forecasts. Values are shown in gr/m³, meaning pollen grains per cubic metre summed over today.
From London to Athens, each city page shows a 4-day forecast chart plus a month-by-month overview based on previous years.

Pollen Types
Tree, grass, and weed pollen can trigger allergic rhinitis. Each type has its own season. Our guides explain symptoms, seasons, and ways to reduce exposure:
- Alder Pollen: Early-spring tree pollen, common in wet, cooler parts of Europe.
- Birch Pollen: Widespread temperate tree pollen, early to late spring.
- Grass Pollen: Late spring and summer, one of the most common allergy causes.
- Mugwort Pollen: Weed pollen, late summer to early autumn.
- Olive Pollen: Mediterranean tree pollen, late spring to early summer.
- Ragweed Pollen: Weed pollen, late summer to autumn, highly allergenic even at low levels.
Pollen Count FAQ
Is the pollen count high today?
It depends on your city and the pollen type. Check the top counts above or open your city page for today's levels. Each type uses its own bands. Grass and ragweed count as high from 30 gr/m³ in our daily total, while tree pollens such as birch and olive count as high from 100 gr/m³.
What pollen is in the air right now?
That follows the season. Alder and birch dominate spring, grass peaks from May to July, olive peaks from mid April to June in the Mediterranean, mugwort runs July to September, and ragweed runs August to October. The pollen map shows which type is highest today.
What is the pollen count in my area?
Use search at the top of the page to find your city, or open pollen counts near you on the map. We cover more than 2,600 cities across Europe, and forecasts update daily.
What does gr/m³ mean?
It means pollen grains per cubic metre. Our values are the daily total of hourly forecast values for each pollen type, so higher numbers mean more pollen exposure over the day.
Where does the data come from?
Forecasts are modelled estimates based on the CAMS European air quality forecasts. They describe expected conditions, not live sensor measurements.
Which pollen types do you track?
Six types: alder, birch, grass, mugwort, olive, and ragweed. Each has a dedicated guide linked under pollen types with symptoms, season timing, and ways to reduce exposure.
