Diving & Travel Guide to Sal, Cape Verde

About Sal

Sal is the most developed diving destination in Cape Verde, offering an extraordinary combination of volcanic cavern systems, vibrant coral reefs, historic shipwrecks, and encounters with some of the Atlantic's most spectacular marine megafauna. The island's southern coast around Santa Maria serves as the hub of Cape Verde's dive industry, with multiple professional operators running daily trips to over twenty named dive sites ranging from shallow coral gardens to deep walls and dramatic caverns. The famous Blue Room cavern, a partially submerged lava tube illuminated by brilliant blue light filtering through underwater entrances, represents one of the most photographed underwater scenes in the entire Macaronesian region. Beyond the caverns, divers explore the Santo Antao wreck, a steel cargo ship resting at approximately thirty meters that has become a thriving artificial reef colonized by schools of barracuda, jacks, and resident nurse sharks. The island's volcanic geology creates an underwater landscape of extraordinary topographic diversity, with swim-throughs, overhangs, pinnacles, and walls descending into deep Atlantic waters. Seasonal visitors include humpback whales during their February to May breeding migration, whale sharks from July through November following plankton blooms, and large pelagic species including tuna, wahoo, and various shark species that patrol the island's exposed oceanic coastline year-round. Water temperatures range from a comfortable twenty-one degrees in winter to twenty-seven degrees in late summer, with visibility typically between fifteen and thirty meters during the calmer months from May through November.
