Residents across Antigua and Barbuda are being advised to take precautions as a fresh surge of Saharan dust descends on the twin-island nation, with the national meteorological authority warning that air quality will deteriorate and remain at reduced levels through mid-week.
The Antigua and Barbuda Meteorological Service has issued a moderate air quality alert as a surge of Saharan dust is expected to affect the country from later tonight through Wednesday. The service said air quality is forecast to fall to moderate levels due to increased concentrations of particulate matter associated with the ninth notable Saharan dust event of 2026.
Air Quality Index values are expected to range between 60 and 80, corresponding to Alert Level II.
Who Is Most at Risk
While the health risk is considered low for most people, officials said unusually sensitive individuals — particularly those with asthma and other respiratory conditions — could experience adverse effects. People with respiratory or heart disease, the elderly, and children are considered most at risk.
The Meteorological Service advised active adults, children, and individuals with respiratory illnesses to limit prolonged outdoor exertion during the period.
A Recurring Pattern in 2026
The latest advisory marks the ninth such dust event recorded in Antigua and Barbuda this year alone, underscoring how frequently the phenomenon is affecting the Eastern Caribbean during the current season. Saharan dust, carried westward across the Atlantic by trade winds, typically intensifies between May and October, coinciding with the region’s wet season.
While the dust can reduce visibility and create hazy skies, it also plays a known role in suppressing early-season tropical cyclone development by introducing dry, stable air into the atmosphere — a dual-edged phenomenon that meteorologists continue to monitor closely.
