Malta’s Spring skies turn orange: Saharan dust clouds air quality

It’s not just your eyes playing tricks. The sun has indeed taken on an eerie orange hue, casting an apocalyptic glow over Malta’s usually azure skies. The culprit? A thick blanket of Saharan dust, thousands of miles away but now blanketing our islands. This isn’t just a visual spectacle; it’s a serious health concern as air quality levels hit dangerous highs.

From Sahara to St. Julian’s

Originating from the Sahara Desert, these dust clouds travel across the Mediterranean, carried by strong winds. Malta’s meteorological office has been tracking this phenomenon, warning of poor air quality since late March. Locals in areas like St. Julian’s and Sliema have been the first to notice, waking up to find their cars and balconies dusted in a fine orange powder.

Air quality: A silent threat

While the orange skies make for dramatic photos, the real story is what we can’t see. Fine dust particles, PM10 and PM2.5, are tiny enough to bypass our natural defenses and lodge deep in our lungs. The World Health Organization (WHO) recommends PM10 levels not to exceed 20 µg/m³. On Tuesday, levels in Malta peaked at over 100 µg/m³.

Dr. Anthony Zammit, a local pulmonologist, warns, “These particles can cause or worsen respiratory issues, especially for the elderly, children, and those with existing lung conditions. It’s crucial to limit outdoor activities, keep windows closed, and use air purifiers indoors.”

What’s being done?

Malta’s Environment and Resources Authority (ERA) has activated its dust action plan, monitoring air quality and issuing alerts. Schools have been advised to keep windows closed, and outdoor activities for vulnerable groups are being rescheduled. However, some critics argue that more could be done, such as stricter construction site regulations to prevent local dust generation.

Environment Minister Aaron Farrugia assures, “We’re working closely with local councils and construction companies to minimize local dust generation. We’re also investing in better air quality monitoring systems.”

When will it end?

Weather forecasts suggest the dust cloud will linger until early next week. While it’s difficult to predict exact timelines, we can expect relief once winds shift and blow the dust away. Until then, Malta’s skies will remain orange, and our lungs will bear the silent burden.

So, what can you do? Keep windows closed, use air purifiers, and limit outdoor activities. Let’s hope that the next time Malta’s skies turn orange, it’s just a beautiful sunset, not a sign of poor air quality.
