About Pollen.Today

What is Pollen.Today?

Pollen.Today is a free pollen forecast service for Europe. It shows current pollen levels, hourly forecasts for today and tomorrow, a multi-day pollen outlook, and personalized allergy risk based on your selected allergens. Data comes from the Copernicus Atmosphere Monitoring Service (CAMS).

How it works

Pollen data comes from the Copernicus Atmosphere Monitoring Service (CAMS), which models airborne pollen concentrations for birch, grass, alder, mugwort, olive, and ragweed across Europe. Weather data (temperature, humidity and weather type) comes from the Open-Meteo forecast API.

Free

Pollen.Today is free to use. There are no ads and no accounts, and we do not sell data.
