Each panel is one allergen: the line is its forecast concentration in grains per cubic metre, hour by hour across today and tomorrow. The dashed lines mark where it crosses into low, moderate and high. Those thresholds differ per pollen type, so the same height means different things from panel to panel. An allergen is left out when your profile excludes it, or when no pollen is forecast for it over these two days.

What to expect

Pollen in Arezzo today is led by ragweed, which tops out at 22 grains/m³ — a high reading — in the morning; right now the count sits at 1 grain/m³. Levels hold moderate or higher between roughly 09:00 and 19:00, easing off outside that window. The rest of today's pollen comes from grass at 3 grains/m³ (low) and mugwort at 2 grains/m³ (low).

Tomorrow shouldn't change much — expect a high peak again in the morning. Over the coming 3 days the picture is Thursday high, Friday high, and Saturday high — Friday looks the strongest.

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.

Pollen risk levels

None
Low
Moderate
High
Very High

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.
