Cape Verde is Atlantic diving, not Caribbean reef diving, and Sal is where almost everyone bases themselves. Expect lava rock, caves and wrecks in Santa Maria bay rather than coral colour, with nurse sharks, rays and loggerhead turtles as the draw. Water runs roughly 22°C to 27°C by season, and the flight from the UK is about six hours.
Two questions come up every time. Is the shark thing real, and does the diving justify packing a regulator?
Where these islands actually are
Cape Verde is a volcanic archipelago of ten islands, roughly 570 km west of Senegal at about 16° north. That is the latitude of Guadeloupe, which is why people arrive expecting Caribbean water. The Canary Current runs south past the islands carrying cooler, nutrient-heavy water, and upwelling brings more of it up. That one fact explains most of what this diving is, and is not.
What you dive here is rock. Basalt walls, arches, boulder fields, lava tubes and caves, with sponges and sea fans on them and black coral deeper down. Hard corals exist as a handful of species growing in patches, not the reef-building machinery of the Red Sea or the Indo-Pacific. What the cooler, richer water gives instead is fish in quantity, an unusually high share of species found nowhere else in the Atlantic, and animals with some size to them.
Which island you dive from
In practice, Sal. It has the dive centres, the boats, the wrecks a few minutes off its own pier and the hotel stock for a mixed party. Boa Vista takes the same direct UK flights and has a couple of operations, but the diving is thinner and more exposed. Everything else means a connection through Lisbon and diving with whoever is running that season.
| Island | Getting there from the UK | What the diving gives you | The catch |
|---|---|---|---|
| Sal | Direct, about six hours, mostly weekly departures | Wrecks at 28 m and 11 m minutes off the pier, lava caves, nurse sharks and rays | Flat, dry island; the better sites need a settled sea |
| Boa Vista | Direct, about six hours, mostly weekly departures | Reefs and caves, humpbacks March to May, the main loggerhead nesting beaches | Few centres and more exposure, so no fallback when a boat cancels |
| Santiago | Via Lisbon, or an inter-island hop | Diving off Tarrafal, on the most Cape Verdean island to spend time on | Diving is a side dish, not the reason to come |
| São Vicente and Santo Antão | Via Lisbon, then a ferry for Santo Antão | Limited diving off Mindelo; Santo Antão is the walking island | No dive infrastructure worth building a week around |
None of that makes the other islands a mistake; it makes them a second week rather than a first. If you are weighing up diving holidays in Cape Verde for the first time, plan around Sal and treat anything else as an add-on you arrange once there.
What you actually see, and what Shark Bay really is
Start with the part that gets mis-sold. Shark Bay — Baía dos Tubarões, on the east coast near Pedra de Lume, around 25 km from Santa Maria by road — is not a dive site. Juvenile lemon sharks, most under two metres, move into a shallow sandy lagoon on the higher part of the tide, and guides walk you out knee to waist deep to watch them pass. It is worth an hour of your week, it runs to the tide table rather than to the clock, and no scuba is involved. Do it. Do not book a country for it.
The sharks you dive with are nurse sharks: Atlantic nurse sharks, two metres and up, lying under ledges and out on the sand. They are not tied to one site. The ones we hear about most often come off the Santo Antão wreck, out of the caves at Três Grutas, and from the tunnel systems at Buracona and Regona over on the north-west side — which is one more reason the calm half of the year matters, because those north-west sites are exactly the ones the wind takes away. The other site worth asking your centre about is Choclassa, a rocky pinnacle roughly 3 km off Santa Maria with its top at about 13 to 14 m and the sand at around 30. It is a short ride, 15 to 20 minutes, it can run current, and it is among the first to be called off on a windy morning.
Beyond that: stingrays and spotted eagle rays, big morays, barracuda, jacks and tuna moving through, groupers, octopus and lobster in the rock, and loggerhead turtles in real numbers through the second half of the year. Visibility is typically 15–25 m, better on a settled day, though the same nutrients that feed the fish take the edge off it.
The wrecks in Santa Maria bay
The wrecks are not a road trip, whatever you may have read. Most centres sit in Santa Maria on Sal and the boats go from the pier at the end of the town, with the wrecks a matter of ten or fifteen minutes out into the bay. Palmeira, the working harbour on the west coast about 4 km from Espargos, is the drive you make for the north-west cave dives, not for the wrecks.
The Kwarcit is the one worth the trip: a 50-metre Russian-built fishing trawler sunk deliberately in January 2006, sitting upright with the sand at about 28 m and the deck at around 23. It is intact enough to swim the deck, look into the holds and take in the whole vessel in one dive, and it holds fish. One warning about names. Plenty of centres, guides and dive-site listings call this same hull the Boris, so if a price list offers you both, check whether you are being sold two dives or the same one twice. The Santo Antão is the genuinely separate wreck and the shallow one: a 55-metre cargo ship that went down in 1966 and now lies broken into three sections in about 11 m, which makes it the second dive of the morning rather than the reason for the trip. There is a third hull, the Sargo, put down on the sand in the same bay, though it gets dived less.
Two things to plan for. The Kwarcit is a proper 28 m dive in Atlantic water, so bottom times are short, nitrox is worth having, and most centres want an Advanced qualification or an equivalent logbook for it. And the rhythm is two-tank mornings: a seven-night stay is realistically 10 to 12 dives before the weather takes its cut.
When to go, and what the wind does to your week
The north-east trades blow hardest from roughly December to April. That is why Sal fills with kitesurfers in January, and why the exposed north and west coast sites, including the lava caves at Buracona and Regona that you reach by road via Palmeira, are often off the table then; boats work the sheltered south and south-west instead. From about August to November the sea settles, the caves come back into play and visibility is at its best.
Two wildlife seasons pull in opposite directions. Humpback whales breed in these waters from about March to May, with the sightings concentrated in March and April — a boat trip rather than a dive, though in season you can sometimes hear them singing while you are down. Loggerhead turtles nest from around June to October, peaking in August, with hatchlings coming off the beaches from late August right through to December; Cape Verde holds one of the largest loggerhead nesting populations in the world, and around two-thirds of it is on Boa Vista.
So the whales sit in the windy, cool half of the year and the turtles in the calm, warm half. If the diving is the point, go late August to November.
What the water does, and what suit to bring
The water is coldest in February, March and April at roughly 22 to 23°C, occasionally a shade under. It creeps up through May and June, reaches about 24°C in July, and peaks in September and October at about 26–27°C. Those are typical figures rather than promises — an upwelling can take a couple of degrees off a given week.
A 5 mm full suit is the safe answer year-round. Add a hood and a vest for February to April, particularly for repeated dives on the Kwarcit with a surface interval in the wind. A 3 mm is comfortable from September to November if you run warm. Bring your own if you can: rental stock on a small island is a lottery, and fit matters more here than in 29°C water.
What it costs you in travel time
About six hours, direct, from the UK to Amílcar Cabral airport near Espargos. Santa Maria is 18 to 20 km south, so 20 to 25 minutes in a transfer. Departures from most UK airports run weekly rather than daily, so in practice you are buying seven or fourteen nights rather than any length you fancy — check the departure day before you book leave.
The part people underrate is the clock. Cape Verde runs one hour behind the UK in winter and two behind during British Summer Time, so there is no jet lag either way. You land in the afternoon and you are on a boat the next morning with a clear head. Against a long-haul Indian Ocean trip, that is worth a couple of dives.
Two pieces of admin. UK passport holders need no visa for a short stay, but you must complete the online pre-registration and pay the airport security fee before you fly, not on arrival — do it at least five days out, because airlines now check for it at the UK gate. And check your insurance covers evacuation off the island; medical cover here is thinner than in Egypt.
If someone in the party isn’t diving
Sal is unusually good at this. Santa Maria has a long, pale beach that shelves gently, warm water and reliable sun, and the hotels sit along it. The adults-only Meliá Llana Beach Resort and Spa is the one we book most for couples where only one of them dives, largely because the boats leave from the town pier at the end of the same beach.
Away from the beach there is the salt crater at Pedra de Lume, which you can float in, the blue-lit cave at Buracona seen from the land, and a serious kitesurfing scene from December to April on exactly the wind that is chopping up your dive sites. Turtle hatchling walks run with the conservation projects in season.
With children the calculation changes, and so does the hotel: the Meliá Llana takes over-16s only, so a family books elsewhere on the same beach. Short transfers and gentle shelving still make Sal easier than most on family dive holidays, but be straight with yourself about the diving on offer. The signature dives are a 28 m wreck and an offshore pinnacle, so a junior diver will be doing shallower, different dives from you rather than tagging along.
Be clear-eyed about the island itself. Sal is flat, dry and brown, with almost no rain and little to look at. It does the beach, the sun and the short transfer well, and that is the deal.
Who this isn’t for
If what you want from a dive is colour — soft coral, anthias, a wall that looks like a garden — this will feel bare, and you will spend the week comparing it unfavourably with somewhere else. That is not a failing of Cape Verde, it is the Atlantic. Divers in that camp are better served by the Red Sea; it is worth reading how the Red Sea bases compare first.
If you cannot afford to lose days, look at the calendar before you write off the island. Swell and surge cancel dives here more often than most people expect, and in the trade wind months a seven-night week can lose two or three mornings. That is a December-to-April problem rather than a Cape Verde problem, though: the same week in late September or October rarely reads like that, and booking the calm half of the year fixes most of it. If your leave is fixed in the windy months and you have a number of dives you want logged, then a sheltered bay such as Soma Bay is the safer purchase, because the boats there go out on days when Sal’s would not.
And if nobody in the party is certified yet, this is not where we would send you to start. You can learn on Sal, and people do, but Atlantic surge makes the first four dives harder than they need to be. If the trip is really a learn to dive holiday, choose the destination around the course and come here for your second or third dive trip instead.
Who it does suit: divers with a fair few dives logged who want big-ish animals, sound wrecks and lava topography, who value a six-hour flight and no time change more than they value coral, and who can shrug when a morning is blown out. If that is you, and particularly if you travel with someone who wants a beach rather than a boat, a week diving in Cape Verde from late August to November is a sensible use of a week off.
Frequently asked questions
Is Cape Verde worth diving if you have already dived the Red Sea?
It is a different product rather than a weaker one. You give up coral colour and reef-fish variety, and you gain lava topography, caves, a 28-metre wreck and a shallow one to pair it with, nurse sharks and rays. Sea state is less dependable than the Red Sea and you should expect to lose the odd morning. If you go expecting a cheaper Red Sea you will be disappointed; if you go for Atlantic rock and animals, it holds up.
Can you really swim with lemon sharks at Shark Bay on Sal?
Yes, but it is a wade rather than a dive. Juvenile lemon sharks, mostly under two metres, move into a shallow sandy lagoon on the east coast near Pedra de Lume on the higher part of the tide, and guides walk small groups out knee to waist deep to watch them. It runs to the tide table, takes about an hour, and involves no scuba at all. Treat it as an excursion, not as your diving.
When is the best time of year to dive Cape Verde?
Late August to November. The north-east trades ease, the exposed north and west coast sites including the Buracona caves become reliably diveable, visibility is at its best and the water peaks around 26 to 27 degrees in September and October. December to April is the windy half of the year, when boats stay on the sheltered south coast and cancellations are common. March to May is the humpback window, but you pay for it in lost sea days.
How deep are the wrecks off Sal and what qualification do I need?
The Kwarcit sits upright with the sand at about 28 metres and the deck at around 23, ten or fifteen minutes by boat from the Santa Maria pier. Many centres list the same hull as the Boris, so check you are not being sold it twice. The Santo Antão is a separate, much shallower wreck at about 11 metres and usually serves as the second dive of the morning. Most centres want an Advanced qualification or a logbook showing comparable experience for the Kwarcit. Nitrox is worth taking, because on air the bottom times are short and the second dive gets restricted.
What wetsuit do you need for diving in Cape Verde?
A 5 mm full suit works all year. The water is coolest from February to April at around 22 to 23 degrees, sometimes a little less, and warmest in September and October at about 26 to 27 degrees. Take a hood and a vest for the cool months, especially for repeated dives on the 28-metre Kwarcit with a windy surface interval. A 3 mm is fine from September to November if you run warm. Bring your own if you can.
