If you get hay fever, you already know the question that matters on a bright spring morning: is it going to be a bad day? This hub answers it with live data — a map and ranked list of current pollen levels across Europe, drawn from the Copernicus CAMS atmosphere model. The block above lists the worst-affected cities right now, each tagged with the dominant pollen driving symptoms there.
Open the live map and switch on the Pollen layer to see every monitored city, each dot colored by how high its pollen is and which type leads.
The six pollens this tracker follows
Not all pollen is equal, and not all of it peaks at once. The map tracks the six that matter most for allergies, and they arrive in a rough seasonal order:
- Alder — late winter into early spring, one of the first tree pollens of the year.
- Birch — spring, and a notoriously potent trigger across northern and central Europe.
- Olive — late spring, a major allergen around the Mediterranean.
- Grass — late spring through summer, the single most common hay-fever trigger across the continent.
- Mugwort — late summer, a weed pollen that bridges into autumn.
- Ragweed — late summer and autumn, highly allergenic and increasingly widespread.
Each card above names which of these is dominant at a given city, so you can tell a birch-driven April from a grass-driven June at a glance.
Reading the levels the right way
The colored bands — low, moderate, high, very high — follow the grains-per-cubic-metre counts that allergy services use. A few things worth knowing:
- Weather moves pollen. Warm, dry, breezy days lift counts; rain knocks them down by washing pollen out of the air. A rainy morning can buy real relief.
- Time of day matters. Pollen release often peaks in the morning and again in early evening, so the same city can read very differently at 8am and 2pm.
- Local beats national. A single national "pollen count" hides big regional swings. Use the city nearest you, and zoom the map to your own area rather than relying on a country-wide figure.
Pollen and air quality often compound each other — the same warm, stagnant conditions that trap air pollution under a heat dome can make a high-pollen day feel worse. If you're sensitive to both, it's worth checking the air-quality tracker alongside this one, and the map's Air Quality layer sits right next to Pollen for exactly that reason.
A note on what this is — and isn't
This is a live environmental tracker, not medical advice. It tells you what's in the air; it can't tell you how your body will react. If your symptoms are severe or persistent, that's a conversation for a pharmacist or doctor, not a map. What this hub does well is the practical part: a fast, honest read on whether today is a high-pollen day where you are, so you can plan around it.
Frequently asked questions
How high is the pollen count today?
The live block above ranks European cities by their current pollen levels, worst-first, showing which type — grass, birch, ragweed and so on — is dominant at each. Find the city nearest you for the closest read on your local conditions. The map's Pollen layer plots every monitored city so you can zoom to your own region.
Which pollen is worst right now?
It depends on the season. Tree pollens (birch, alder, olive) peak in spring; grass pollen dominates late spring into summer and is the single most common hay-fever trigger; weed pollens like ragweed and mugwort peak in late summer and autumn. Each card above names the dominant pollen at that location so you can see what's driving symptoms today.
Why does the map only cover Europe?
The underlying pollen forecast comes from the Copernicus Atmosphere Monitoring Service (CAMS), whose detailed, species-by-species pollen model covers Europe. Outside Europe there isn't an equivalent free, openly-available pollen feed at the same resolution, so we show Europe honestly rather than display unreliable numbers elsewhere.
Why is the pollen count low or zero where I am?
Outside the main season, many places genuinely read low or zero — that's expected and not a data error. Pollen is highly seasonal: a city buried in birch pollen in April can read near-zero by July, when grass takes over. Levels also drop after rain, which washes pollen out of the air, and rise on warm, dry, breezy days.
How often does the pollen map update?
The CAMS pollen forecast refreshes hourly, and this tracker updates on top of that. Because pollen release follows a daily rhythm — often highest in the morning and early evening — checking at different times of day can show meaningfully different levels.
