Cape Verde sits in warm, nutrient-rich mid-Atlantic water, and its volcanic geology makes for dramatic underwater terrain: sheer drop-offs, lava arches, caves and a scattering of wrecks. Visibility is generally excellent, the water never gets cold, and the dive scene is small enough that sites rarely feel crowded.
Conditions, season and visibility
Water temperatures run between roughly 22°C in late winter and 26°C in late summer, so a 3–5 mm wetsuit is normally enough. Visibility is often 20–30 m, best in the calmer months from roughly May to November. Winter brings more swell and wind, which can close exposed sites — although it also brings the best conditions for wind sports above the surface.
Currents can be strong on exposed coasts and around headlands, so drift dives are common. Follow local briefings closely; see our safety guide for a wider picture of ocean conditions.
Diving on Sal
Sal has the most established dive scene, with several centres based in Santa Maria. Highlights include the Buracona area on the wild north-west coast, the wreck-strewn bay off Santa Maria, cave dives and shallow reefs ideal for training. It is the easiest island for a first dive or a course.
Diving on Boa Vista
Boa Vista is quieter, with fewer centres but big, open sites and a good chance of larger pelagics. Sheltered dives around the islet off Sal Rei suit beginners, while the exposed coast rewards experienced divers when conditions allow.
Santiago and other islands
Santiago has a small dive community based near Praia, with volcanic walls and good fish life. Diving on the smaller islands is generally informal or unavailable, so if diving is the point of your trip, base yourself on Sal or Boa Vista.
What you will see
Expect moray eels, groupers, parrotfish, trumpetfish, octopus, lobster and big schools of grunts and snappers. Rays and turtles are common, nurse sharks appear at some sites, and lucky divers meet whale sharks or manta rays. From March to May, the same waters host humpback whales, occasionally audible underwater.
Choosing a dive centre
Look for PADI or SSI affiliation, well-maintained kit, small group sizes and an instructor who speaks your language confidently. Ask about insurance, the nearest recompression chamber (facilities are limited on the islands) and whether nitrox is available. Comprehensive travel insurance covering diving is strongly recommended.
- Bring your certification card and logbook.
- Leave 24 hours between your last dive and flying.
- Reef-safe sunscreen only — the reefs here are fragile.
- Book courses ahead in winter high season.
Frequently asked questions
Is Cape Verde good for diving?
Yes — warm water at 22–26°C, visibility often 20–30 m, volcanic walls, caves and wrecks, plus plenty of fish. Sal and Boa Vista have the most established dive centres.
When is the best time to dive in Cape Verde?
Roughly May to November, when the sea is calmest and warmest. Winter brings more swell and wind, which can close exposed sites.
Can beginners dive in Cape Verde?
Yes. Sal in particular has sheltered, shallow sites and dive centres offering try-dives and full certification courses.
Are there sharks in Cape Verde?
Yes, including nurse sharks at some dive sites and juvenile lemon sharks in the shallows at Shark Bay on Sal. Dangerous encounters are extremely rare.
