WARNING: Diving with certified operators is of vital importance.


Certified dive operators are trained to ensure diver safety. They follow standard procedures and protocols that minimize the risks associated with diving, such as decompression accidents, loss of visibility, buoyancy problems and other potential hazards. In addition, they have access to emergency equipment and know how to act in emergency situations in the water.


Do you want to become a certified diver?

Certification: If you are not yet a certified diver, you can take advantage of the various certification courses offered on the islands. PADI (Professional Association of Diving Instructors) courses are common and available.

Best Diving Season

The best time to dive the Corn Islands is generally from November to May, when the weather is drier and visibility is optimal. During these months, conditions are more favorable for diving due to the following reasons:

Climate: During the dry season, the Corn Islands, where Corn Island is located, experience a more stable climate with less rain and storms. This translates into calmer waters and better underwater visibility.

Visibility: Underwater visibility tends to be excellent during the dry season, often reaching up to 30 meters or more. This means you will be able to better appreciate the marine life and details of the coral reefs.

Water Temperature: Water temperatures are pleasant during the dry season, generally ranging between 26°C and 30°C (79°F – 86°F), which makes for comfortable diving without the need for thick wetsuits.

Less wind: During the rainy season, which runs from May to October, strong winds and unpredictable currents are more likely, which can make dives more difficult and reduce visibility.

However, it is important to note that Corn Island is a year-round dive destination. During the rainy season, it is possible to dive by obtaining adequate information from local operators.

Marine Ecosystem Preservation.

Be aware of the importance of preserving the delicate marine ecosystems by following responsible diving practices.

Several projects and organizations work on marine conservation in Corn Island and the protection of its marine ecosystems. Some of the conservation projects and actions being carried out in the region include:

Coral reef monitoring: Local organizations and dive groups collaborate to carry out coral reef monitoring programs. This involves conducting regular research to assess coral health, identify threats, and take steps to protect and restore them.

Sea turtle protection: The Corn Islands are an important nesting site for sea turtles, such as hawksbills and green turtles. Conservation projects work to protect turtle nests, educate the local community and visitors about the importance of sea turtles, and conduct patrols to prevent egg poaching and turtle capture.

Coral reef restoration: Active coral reef restoration, which involves rearing corals in marine nurseries and then transplanting them to damaged areas, is a strategy used to help rehabilitate damaged or degraded coral reefs.

Environmental education programs: Local and international organizations conduct environmental education programs in local schools and with the community to raise awareness of the importance of marine conservation and encourage responsible practices.

Marine Debris Cleanup: Removing trash and plastic debris from the marine environment is critical to maintaining coral reef health and protecting marine life. Regular beach and seabed cleanups are organized.


Controlling illegal fishing: Controlling illegal and destructive fishing is essential for the protection of marine resources. Projects work with local fishermen to promote sustainable fishing practices and help enforce fishing regulations.

Support for marine protected areas: Islas del Maiz can establish marine protected areas or marine reserves to conserve critical habitats. Conservation projects work to promote and support these initiatives.

These are just a few examples of the marine conservation projects being carried out on Corn Island. Collaboration between local, national and international organizations, as well as the involvement of the local community and visitors, are essential to ensure the long-term protection of marine life in this incredible region of the Caribbean.
