Attard · Malta · Background · Urban
Conditions across the Maltese Islands that may be influencing air quality. Context explains a reading; it never adjusts one, and it does not establish the cause of any individual measurement.
The CAMS model forecasts mineral dust concentrations peaking near 34 µg/m³ over the Maltese Islands, with an aerosol optical depth of about 0.35. Dust transported from North Africa may contribute to elevated PM10 and, to a lesser extent, PM2.5. Dust is a natural source, but the particles it adds affect health in much the same way as other coarse particulate matter.

Wind speeds are forecast to fall to about 0.8 km/h for around 10 hours. Light winds may allow locally emitted pollutants — traffic nitrogen dioxide and fine particles in particular — to accumulate near the ground instead of dispersing.

Hourly values as published, including hours the feed filled in by modelling.
The published feed carries roughly ten days of hourly history and about two days of forecast, so no longer window is offered. Hours the instrument did not report are shown as gaps. This view covers 65 hours from Sat 12 Sep, 20:00 to Tue 15 Sep, 12:00.
Concentration (µg/m³)
Time (Malta)
PM10, coarse particulate matter at Attard, hourly, in µg/m³, covering the last 24 hours. The published points run from Sat 12 Sep, 20:00 to Tue 15 Sep, 12:00. 65 hours are shown: 0 measured, 0 filled in by modelling, 0 forecast, and 65 with no value at all. No directly measured value is available in this window, so no minimum, maximum or average can be given.

Figures cover directly measured hours only. Modelled and forecast hours are excluded from the minimum, maximum and average. Near-real-time data is published before validation and may be revised or withdrawn by ERA.
Some past hours are modelled too: the feed fills gaps when an instrument does not report. Those points are marked as estimated. All times are shown in Malta time.
PM10 — Not available
There is no current value for this pollutant, so it cannot be compared with any limit or guideline.
Advice for the current band: Fair
Outdoor activity remains fine for the general population.
A small number of unusually sensitive people may notice mild symptoms during long outdoor exertion.
Advice here is general and precautionary. Air quality is one factor among many, and staying active remains beneficial. If you have severe or sudden symptoms, seek medical help rather than relying on this page.
maqua.app provides general environmental information and does not replace medical advice or official emergency guidance.
Forecast values are model output, not measurements. Modelled estimates from the Copernicus atmosphere service, carried in the same feed.

Saharan dust forecast over the islands
Mineral dust is forecast over the Maltese Islands, peaking near 34 µg/m³. Dust transported from North Africa may contribute to particulate levels, particularly PM10.

Winds are forecast to average about 7 km/h. Light winds may allow locally emitted pollutants to linger rather than disperse, particularly overnight and near busy roads.

About 1.6 mm of rain is forecast. Rainfall may wash particulate matter out of the air and reduce the dust lifted by traffic.

Air-quality data provided by Malta's Environment and Resources Authority (ERA), disseminated via the European Environment Agency (EEA). maqua.app is an independent project and is not operated by, affiliated with, or endorsed by ERA or the EEA.
Each pollutant concentration is rounded to the nearest whole microgram per cubic metre and matched against the published band ranges. The location takes the band of its worst pollutant. A missing value is shown as unavailable and never as zero. Bands are calculated only from pollutants that actually reported.
This is not an official ERA or EEA service. For official statements, consult ERA directly.
