About the Pollen Forecast

What is a pollen forecast?

A pollen forecast predicts the concentration of airborne pollen grains (measured in grains per cubic meter) for a specific location and time. Pollen is released by trees, grasses, and weeds during their pollination seasons. Higher concentrations trigger worse allergy symptoms in sensitive individuals. This forecast uses data from the Copernicus Atmosphere Monitoring Service (CAMS).

How do I check the pollen forecast today?

This page shows the live pollen levels for your location using data from CAMS via Open-Meteo. You get current pollen concentrations for birch, grass, alder, mugwort, olive, and ragweed — plus an hourly forecast chart and tomorrow's outlook. Select your allergens to see personalized risk levels.

When are pollen levels highest?

Pollen levels vary by type: tree pollen (birch, alder) typically peaks in spring mornings, grass pollen peaks in late spring and summer afternoons, and weed pollen (mugwort, ragweed) peaks in late summer and fall. Warm, dry, windy days have higher pollen counts. Rain temporarily reduces airborne pollen. Check the forecast chart above for today's exact pollen trend.

How can I reduce pollen exposure?

Many people reduce pollen exposure by keeping windows closed on high-pollen days, showering after time outdoors, and using air purifiers. Check the pollen forecast before outdoor activities, and consult a healthcare provider for personal advice.

What is an allergy profile?

Your allergy profile tells us which pollen types trigger your symptoms. Different people react to different pollens — some are allergic to birch and grass, others to ragweed or olive. By selecting your allergens, you get a personalized risk assessment that only considers the pollen types relevant to you, rather than a generic overall forecast.

How are pollen risk levels calculated?

Risk levels are based on approximate pollen concentration thresholds per allergen type (grains/m³):

  • Tree pollen (birch, alder): Low ≤10, Moderate ≤100, High ≤1000, Very High >1000
  • Grass & weed pollen (grass, mugwort, ragweed): Low ≤5, Moderate ≤20, High ≤50, Very High >50
  • Olive pollen: Low ≤10, Moderate ≤50, High ≤200, Very High >200

Your risk is the highest level among your selected allergens. These approximate thresholds are commonly referenced in European aeroallergen research (EAN) and clinical guidelines.
