Country air quality
Denmark Air Quality Index 2026
Live air quality for Copenhagen and major cities, plus national PM2.5 exposure trends for Denmark.
Denmark's latest national PM2.5 exposure is 9.1 µg/m³ (2020). Live AQI readings below are city-level snapshots, starting with Copenhagen.
LIVE
Live air quality in Copenhagen
This live reading uses Copenhagen's coordinates. It is useful for current conditions, but it should not be treated as the air quality for all of Denmark.

Live AQI across major cities in Denmark
City readings can differ sharply because traffic, smoke, dust, wind, rain, and topography are local. Compare several populated places before drawing conclusions about the country.

National context
National PM2.5 exposure trend in Denmark
PM2.5 is a population-weighted annual exposure indicator, so it is better for long-term country comparisons than for today's local conditions.
How to read this page
The live cards show city-level AQI from Open-Meteo at specific coordinates, led by Copenhagen. The national PM2.5 chart shows annual population-weighted exposure for Denmark. These are related, but they are not the same measurement.
Sources and limits
Live AQI, PM2.5, PM10, UV, and pollen context come from Open-Meteo's air-quality API. National PM2.5 exposure comes from the World Bank indicator EN.ATM.PM25.MC.M3. Local official alerts should take priority during smoke, dust, or pollution events.
Air quality FAQ
No. Live AQI is local, so this page shows city readings for Denmark, starting with Copenhagen. The national PM2.5 chart is the country-level long-term indicator.
National PM2.5 is the population-weighted annual mean exposure to fine particulate matter. It is useful for country comparisons, but it is not a live forecast.
The live city AQI endpoint is cached briefly, usually around 10 minutes, to keep readings fresh while reducing upstream load.
Air pollution is highly local. Traffic, industry, wildfire smoke, dust, wind, rain, altitude, and urban layout can make one city in Denmark much cleaner or dirtier than another on the same day.
