Air Quality Index (AQI) in Malta 🇲🇹

Live Air Quality Index (AQI) and PM2.5 Levels in Malta

Currently, the Air Quality Index (AQI) in Valletta, the capital of Malta, is measured at a score of 54. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Valletta is influenced by a PM2.5 (fine particulate matter) concentration of 10.6 µg/m³ and PM10 levels recorded at 17.7 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 9.1 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Malta based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like San Pawl il-Baħar, Birkirkara, Mosta, Sliema and Qormi. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.

Air Quality Snapshot: Malta Right Now

Across 6 monitored cities in Malta, live air quality currently ranges from a low of 44 AQI in San Pawl il-Baħar (the cleanest air right now) to a high of 54 AQI in Mosta (the most polluted). By US EPA health band, the nationwide distribution stands at 2 Good, 4 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 9.5 µg/m³ — approximately 1.9 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

* Air Quality Index (AQI) data for Malta is calculated using the US EPA standard. Information is processed from multiple monitoring stations detecting PM2.5, PM10, and gaseous pollutants to ensure accuracy for respiratory health planning.

What Today's Readings Mean in Malta

The median reading across 6 monitored cities is 52.0 AQI. The national spread is 10 points, from 44 in San Pawl il-Baħar to 54 in Mosta. Average PM2.5 is 9.5 µg/m³ (1.9× the WHO annual guideline).

At least one monitored location is in the Moderate range. People unusually sensitive to air pollution may want to reduce prolonged outdoor exertion there.

Air Quality in Malta — FAQ

Common questions about AQI levels, pollutants, and data sources for Malta.

What is the current air quality in Malta?

Live AQI readings for 6 city(ies) across Malta are listed above on the US EPA 0-500 scale.

Where does Malta's AQI data come from?

Real-time readings come from ground-based monitoring stations operated by national environmental agencies in Malta, delivered via WeatherAPI.com and aggregated using the EPA AQI formula.

What is a healthy AQI value in Malta?

On the EPA scale used worldwide, 0-50 is Good, 51-100 is Moderate, 101-150 is Unhealthy for sensitive groups, 151-200 is Unhealthy, 201-300 is Very Unhealthy, and 301-500 is Hazardous. The WHO 24-hour PM2.5 guideline is 15 μg/m³.

Why do AQI readings vary between cities in Malta?

Air quality is highly local — major pollution sources (traffic, industry, dust, wildfires) cluster around cities, while wind direction and topography move them around. Comparing nearby readings on this page is the best way to see how conditions change across Malta.
