Saharan Dust Surge Set to Deteriorate Air Quality Across Caribbean

A fresh wave of Saharan dust is on its way to the Caribbean, prompting meteorological services in various islands to issue alerts regarding deteriorating air quality. 

In Antigua and Barbuda, meteorologist Dale Destin highlights that the season for Saharan dust, which officially began in mid-February, is now experiencing its second significant surge.

This afternoon is expected to mark the arrival of the dust cloud in Antigua, leading to moderate reductions in air quality due to higher levels of particulate matter. Destin has indicated that this situation is likely to persist for several days, with air quality projected to remain compromised until at least early next week, though a brief respite is anticipated on Saturday.

While the overall health risk is considered low for the general population, those with respiratory sensitivities—such as asthma patients—are advised to take precautions and stay updated on air quality reports.

Meanwhile, neighboring islands are bracing for similar conditions. The Grenada Meteorological Service has announced it is keeping a close eye on this dust plume traveling across the Atlantic from North Africa.

Their advisory indicates that dust concentrations could vary from moderate to dense at times, impacting air quality from tomorrow potentially into early next week.

Destin pointed out that while Saharan dust can be present throughout the year, its effects are most pronounced from mid-February to mid-November, with peak concentrations typically seen in June. During this peak season, Caribbean islands usually experience dust events every three to five days.
