24 June 2026 | Press Release | By: MHES Communications

The Ministry of Health, Environment and Sustainability (MHES) and the Public Health Department (PHD) are advising residents to take precautions to protect themselves from the effects of Saharan dust. The Cayman Islands National Weather Service (CINWS) has issued a Dust Alert in effect from Friday, 26 June through Sunday, 28 June 2026.

Saharan dust is a mixture of dust and sand that travels thousands of miles from the Sahara Desert to the Caribbean each year. These events can reduce air quality and affect respiratory health, particularly among vulnerable individuals. Symptoms associated with exposure may include coughing, wheezing, sore throat and shortness of breath.

“Most people may experience only mild symptoms, but young children, older adults and persons with asthma or other chronic respiratory conditions are at increased risk,” said Acting Chief Medical Officer Dr. Mark Paramlall. “Limiting time outdoors, keeping doors and windows closed and ensuring medications are readily available can help reduce the health impacts associated with poor air quality. Anyone experiencing worsening respiratory symptoms should contact their healthcare provider.”

“Seasonal Saharan dust events are a normal occurrence in the Caribbean, and while they can be uncomfortable, the health effects are generally temporary and manageable,” said Medical Officer of Health Dr. Samuel Williams-Rodriguez. “Simple measures such as reducing outdoor exposure, staying hydrated and following treatment plans for existing respiratory conditions can go a long way in protecting your health. We encourage residents to stay informed through official channels and to seek medical advice if symptoms become severe or persistent.”

Based on information provided by the Cayman Islands National Weather Service, the effects of the dust cloud are expected to begin on Friday and persist through Saturday.

MHES and PHD are issuing the following public health guidance:

General public

  • Limit time outdoors, particularly during periods of high dust concentration.
  • Keep doors and windows closed to reduce dust entering homes and buildings.
  • Use air conditioners on recirculation mode or air purifiers, if available.
  • Wear long-sleeved clothing and protect eyes from irritation.
  • Wash hands regularly and avoid touching eyes.
  • Monitor for new or worsening symptoms and seek medical advice if necessary.

Persons with asthma or other respiratory illnesses

  • Remain indoors where possible and use air conditioning on recirculation mode.
  • Ensure reliever inhalers and medications are readily available.
  • Consider wearing a well-fitting face mask when outdoors if exposure cannot be avoided.
  • Contact a healthcare provider if symptoms worsen.

Schools and workplaces

  • Limit outdoor activities, including sports and prolonged breaks.
  • Keep windows closed where practical.
  • Inform parents and caregivers of measures being taken to protect vulnerable children.

MHES and PHD will continue to work closely with CINWS to monitor conditions and provide updates as necessary. Residents are encouraged to follow official government channels for the latest information.
