A new wave of Saharan dust is making its way across the Atlantic Ocean towards the Caribbean, prompting meteorological services across several islands to issue advisories regarding reduced air quality.

Antiguan meteorologist Dale Destin has alerted residents that “the Saharan dust season, which officially began in mid-February, is now bringing the second notable surge of the year to Antigua and Barbuda.”

The dust cloud is expected to reach Antigua this afternoon, leading to a reduction in air quality to moderate levels due to elevated concentrations of particulate matter. Destin indicated that these effects are likely to persist for several days, with air quality remaining diminished “through at least early next week,” although a temporary break is anticipated on Saturday.

While the health risk remains low for most individuals, those who are particularly sensitive—such as people with asthma or other respiratory conditions—are advised to take precautions and stay updated on the latest air quality information.

Neighboring islands are bracing for similar conditions. The Grenada Meteorological Service has reported that they are closely monitoring the same dust plume as it travels from North Africa. Their advisory indicates that dust concentrations could range from moderate to potentially dense at times, with effects expected to begin tomorrow and possibly extend into early next week.

Destin explained that while Saharan dust is present throughout the year, its impact is most pronounced from mid-February to mid-November, with peak concentrations typically occurring in June. During this period, the Caribbean usually experiences dust events every three to five days.

Historical data from Météo-France highlights that one of the most severe dust events in recent memory occurred in June 2020 when air quality plummeted to “very unhealthy” levels—the worst recorded in over 50 years. Experts have noted that early 2025 has already seen higher-than-normal dust concentrations; however, long-term seasonal forecasting for Saharan dust activity remains limited to just a few days ahead.

As residents prepare for the impending arrival of Saharan dust, authorities urge vigilance and adherence to health advisories to mitigate any potential impacts on respiratory health.
