French Caribbean reefs, wrecks and volcano views in one compact island
Updated Nov 21, 2025 • 10 sources
Martinique offers solid safety infrastructure for a tropical island, with French standard emergency services, a hospital based hyperbaric chamber and well established dive centers that follow international training agency standards. Most diving takes place on the sheltered Caribbean side in recreational depth ranges, but deep wrecks, occasionally lively currents and Atlantic hurricane season all deserve respect. Conservation is central to local policy through the Parc naturel marin de Martinique and the Agoa Marine Mammal Sanctuary, both of which enforce rules on anchoring, fishing and wildlife interactions.
Stick to conservative profiles, especially on deep wrecks in Saint-Pierre Bay and offshore pinnacles where depths can exceed 40 m quickly. Use a dive computer, SMB and audible surface signal on every dive and agree on gas reserves and maximum depths with your guide. Most centers follow PADI, CMAS or FFESSM standards and will request proof of certification and recent experience for sites like Le Roraima or La Perle. Avoid decompression diving unless you are trained, equipped and working with a center that supports that level. Leave at least 18 to 24 hours between your last dive and flying.
As a French department, Martinique benefits from good quality medical care. The Centre Hospitalier Universitaire in Fort-de-France hosts hyperbaric facilities that serve divers from across the French West Indies, and emergency doctors are familiar with treating dive related incidents. In an emergency, locals dial 15 for SAMU (medical), 18 for fire and rescue or 112 from mobile phones, and maritime incidents are coordinated by CROSS Antilles-Guyane on VHF 16 or by dialing 196. Divers should still carry dedicated dive accident insurance and understand that remote north coast or Atlantic sites may have longer evacuation times.
Hurricane season and heavy squalls
From roughly June through November, particularly August to October, Martinique lies in the Atlantic hurricane belt. Most years pass with only distant storms and short lived squalls, but the risk of tropical systems increases significantly. Build flexibility into your itinerary, buy travel insurance that covers weather disruptions and follow local guidance on when to stay ashore.
Currents and depth on northern wrecks
Wrecks in the Bay of Saint-Pierre, including Le Roraima, Le Dahlia and deeper historical sites, sit between about 30 m and beyond 50 m. Even in mild current this leaves little room for error, so they are best reserved for experienced divers with advanced or deep training, redundant computers and conservative gas plans. Never push no deco limits here.
Surge and boat traffic at pinnacles
At Rocher du Diamant, La Perle and other offshore rocks, surge can be strong even when wind seems modest and boat traffic from multiple dive centers converges in small areas. Always carry an SMB, stay close to your guide, avoid surfacing away from the planned ascent point and ensure skippers know where freedivers or snorkelers are in the water.
Sun, fire coral and occasional stingers
Tropical sun, reflective water and long boat days make sunburn and dehydration more likely than shark encounters. Wear full coverage rashguards, hydrate and avoid touching the reef to prevent fire coral stings. Jellyfish and small stinging plankton sometimes appear after squalls, so consider a thin suit even for snorkeling if you have sensitive skin.
The Parc naturel marin de Martinique protects coastal waters, reefs, mangroves and seagrass beds, while the wider Agoa Sanctuary safeguards whales and dolphins throughout the French Antilles. Core guidelines are simple: do not touch or collect coral, shells or artifacts; never chase or feed turtles, rays or marine mammals; use provided moorings instead of anchoring on reef; and choose reef safe sunscreen. Wrecks in Saint-Pierre Bay are also designated cultural heritage sites, so penetration, artifact removal and any form of disturbance are strictly prohibited. Supporting local clubs, guides and conservation groups helps keep moorings maintained and monitoring programs funded.
Do Not Do This
Avoid entering when hurricane season and heavy squalls. Confirm local briefings before committing.
