Madeira
Atlantic island walls, marine reserves, and easy add-on days to Porto Santo

Safety And Conservation
Madeira is generally a straightforward destination for guided diving, but it is still open Atlantic. Sea state, surge, and wind can change plans quickly, so prioritize operators that adapt sites to conditions and keep an SMB culture for ascents. Conservation is central to the experience: several prime sites are marine protected areas with specific rules, reservations, and per-dive fees that support management.
Top Risks
- Primary risk: Atlantic swell and surge
- Secondary risk: Rocky shore entries
- Emergency contact: Emergency number (Portugal) (112)
- Safety overview: Madeira is generally a straightforward destination for guided diving, but it is still open Atlantic.
Dive safety
- Swell awareness: If the ocean is moving, avoid rocky shore entries and choose sheltered bays or boat dives in protected water.
- Surface signaling: Carry an SMB and use it for blue-water ascents and whenever you are away from the reef structure.
- Wreck discipline: Treat artificial reefs as living habitat. Do not penetrate unless trained and conditions are stable.
- Buddy and operator briefings: Follow local site briefings closely, especially in reserves with buoy fields and boat caps.
For urgent medical emergencies, call 112 in Portugal. For dive injuries and suspected decompression illness, activate emergency services early and follow professional advice. Madeira has hospital services in Funchal, including a hyperbaric medicine outpatient unit at Hospital Dr. Nelio Mendonca (SESARAM). Your dive operator will typically coordinate evacuation and medical contact if an incident occurs.
Snorkel and freedive safety
Atlantic swell and surge
Swell direction matters more than air temperature. A moderate swell can turn rocky snorkel entries unsafe and can cancel exposed boat sites. Always accept operator cancellations and use sheltered south-coast alternatives.
Rocky shore entries
Many access points are pebbly, rocky, or ladder-based. Wear booties, keep fins on only when stable, and plan an exit before fatigue sets in.
Boat traffic near popular sites
In south-coast bays, boats and swimmers may share the same water. Use a surface float and stay predictable, especially when freediving or snorkeling.
Peak weather changes fast
Mountain fog and wind can arrive suddenly. Bring layers, do not rely on a single viewpoint, and treat closed trails as closed.
Wildlife and protected areas
- Respect marine protected areas: Garajau, Cabo Girao, Porto Santo, Desertas, and Selvagens include zones with special protections. Use SIMplifica reservations where required and do not bypass boat limits or buoy rules.
- Wildlife behavior: Large fish in reserves can be bold. Observe without feeding or touching.
- Leave no trace: Do not collect shells or organisms, avoid standing on rock ledges, and keep fin kicks controlled over algae and sand.
- Sensitive wildlife: Desertas and Selvagens have high conservation value. Treat those trips as strictly observe-only and follow all approach rules.
Do Not Do This
Avoid entering when atlantic swell and surge. Confirm local briefings before committing.
