Saharan Dust Pushes Air Quality to Moderate Levels Across Antigua and Barbuda

A fresh surge of Saharan dust has pushed air quality across Antigua and Barbuda into the moderate category, with meteorologists warning that sensitive groups may experience health effects as dust concentrations remain elevated through Thursday night.

The Antigua and Barbuda Meteorological Service said the country is experiencing its tenth notable Saharan dust event of 2026, with particulate matter levels associated with dust reducing air quality to an Air Quality Index range of 51 to 70 and placing the country under an Air Pollution Alert Level II.

While the overall health risk remains low for most people, authorities said individuals with respiratory or heart disease, the elderly and children are among those most vulnerable to the effects of the dust.

The Meteorological Service noted that air quality remains acceptable for the general population, but a small number of unusually sensitive individuals, including people with asthma, could experience moderate health concerns.

Officials are advising active children and adults, as well as those with respiratory conditions, to limit prolonged outdoor exertion until conditions improve.

The local advisory comes as a massive Saharan dust plume continues its journey across the Atlantic Ocean. Data from the European Union’s Copernicus Atmosphere Monitoring Service showed the dust cloud stretching from the west coast of Africa toward the Caribbean at the beginning of June.

The plume, which affected air quality in countries including Cabo Verde, was forecast to extend across much of the North Atlantic and reach the Caribbean Sea, carrying fine dust particles thousands of miles from the Sahara Desert.

Residents are encouraged to monitor updates from the Antigua and Barbuda Meteorological Service and other official information channels for the latest forecasts and air quality information.
