Pollen Forecast

Check today's pollen levels for any European city or your current location — grass, birch, ragweed and more, with allergy guidance. Free, powered by Open-Meteo.

How It Works

Pick a place and read the pollen — no account, no key.

1

Choose a location

Search for a European city and select it, or tap "Use my location" and allow access. The coordinates are sent to Open-Meteo to fetch the current pollen forecast for that exact spot.

2

Read the overall level

The headline shows the overall pollen level — None, Low, Moderate, High or Very High — based on the strongest allergen in the air right now, with a short line of allergy guidance.

3

See it by pollen type

The grid breaks the reading down by grass, birch, alder, ragweed, mugwort and olive so you know which allergen is high. Also reacting to pollution? Check the air quality index, or plan around the weather with the forecast.

Frequently Asked Questions

What is a pollen count and what is a high level?
A pollen count is the amount of pollen in the air, measured in grains per cubic metre (grains/m³). This tool groups the reading into indicative levels — None, Low, Moderate, High and Very High — for each pollen type, and shows an overall level based on the strongest allergen present. High and Very High levels are when allergy sufferers are most likely to notice symptoms.
Which pollen types does it show?
It shows grass, birch, alder, ragweed, mugwort and olive pollen — the main allergenic types covered by the Copernicus (CAMS) European pollen model. Grass pollen peaks in late spring and summer, tree pollens (birch, alder, olive) earlier in spring, and weed pollens (ragweed, mugwort) in late summer and autumn.
Where does the pollen data come from?
The levels come from Open-Meteo's free Air Quality API, which uses the Copernicus Atmosphere Monitoring Service (CAMS) European pollen model. When you choose a location, your browser requests the current pollen concentrations directly from Open-Meteo and displays them. LK Forge does not run its own pollen sensors.
Does it work outside Europe?
The CAMS pollen model covers Europe, so pollen values are usually only available for European locations. If you search for a place outside Europe the tool will tell you no forecast is available rather than showing blanks. For air pollution anywhere in the world, use the Air Quality tool instead, which uses the global CAMS model.
Is it free and do I need an API key?
Yes — the pollen tool is completely free, and no API key or sign-up is required. Open-Meteo offers free access for non-commercial use, so the tool works straight away with nothing to configure. There is no account, no paid tier and no advertising anywhere on the page.
