Diving & Travel Guide to Boa Vista, Cape Verde

About Boa Vista

Boa Vista is Cape Verde's premier whale watching and large marine life destination, offering extraordinary encounters with humpback whales, whale sharks, and manta rays in crystal-clear Atlantic waters surrounding this flat, desert-like island. The island's extensive sandy coastline and surrounding reefs create ideal conditions for diverse marine ecosystems, with the shallow waters between Boa Vista and nearby Maio serving as a critical breeding ground for humpback whales each winter. The iconic Cabo Santa Maria wreck, a cargo ship grounded on a beach since nineteen sixty-eight, has become both a landmark and an artificial reef attracting diverse marine life. Diving here emphasizes large pelagic encounters, with João Valente Reef offering thrilling shark dives featuring large groupers and reef sharks, while Manta Reef serves as a seasonal cleaning station where manta rays hover motionless for smaller fish. The island's relatively undeveloped tourism infrastructure means fewer divers and more pristine conditions compared to Sal, with operators offering personalized small-group diving experiences. Water visibility regularly exceeds twenty meters during the calm season from May through November, and the island's exposed position in the Atlantic attracts oceanic species including tuna, wahoo, and various billfish. Whale shark encounters are particularly common from July through October when plankton concentrations peak in the surrounding waters.
