The Ministry of Health, Environment and Sustainability and the Public Health Department are advising residents to familiarise themselves with and mitigate against the effects of Saharan dust. The Cayman Islands National Weather Service (CINWS) issued a dust alert effective from today through Thursday, 4 June 2026.
“Saharan dust is a mixture of dust and sand that travels thousands of miles from the Sahara Desert to the Atlantic Ocean, impacting the Caribbean on an annual basis,” explains Chief Medical Officer, Dr. Hilary Wolf. “This dust is expected to reduce air quality and can cause respiratory issues, so it is important that all residents are monitoring official channels to ensure they are taking the necessary steps to protect themselves and their families from the potentially negative impacts associated with the dust cloud.”
Saharan dust can irritate the lungs and make breathing more difficult. “Coughing, wheezing, sore throat and shortness of breath may be experienced while the dust cloud is over us,” explains Medical Officer of Health, Dr. Samuel Williams-Rodriguez. “Persons with asthma or other respiratory conditions are at increased risk, and are advised to take additional precautions during this period.”
“Based on the model predictions provided by our partners at the National Weather Service (NWS), the effects of the dust cloud will begin this evening, and we can expect the heaviest concentration on Wednesday, with a gradual decrease through Thursday,” Dr. Wolf explains.
The model indications are such that MHES and PHD are issuing the following public health guidance:
General public:
- Stay indoors as much as possible
- Close door and windows to keep dust out
- Use air conditioners (set to recirculate) or air purifiers if available
- Wear face masks when outside
- Wear long sleeve clothing and protect eyes
- Wash hands regularly and avoid touching eyes
- Monitor symptoms- dust particles can linger in air for up to 10 days, so monitor for new or worsening symptoms and contact your healthcare provider as needed
Persons with asthma or other respiratory illnesses: Stay indoors with A/C on recirculate. Ensure that reliever inhalers are readily accessible/on hand. Contact physician if there is any worsening of health.
Schools and workplaces: Cancel outdoor sports. Limit outdoor time, including for meals and breaks. Ensure windows are closed. Inform parents of vulnerable children about these measures.
MHES and PHD will continue to work closely with NWS to monitor the situation, and will update the public as needed. Residents are urged to follow official channels for up-to-date information. Persons needing additional guidance or information can contact the Public Health Department on 244-2889 or 244-2621.
