Safety And Conservation

Faial is an open-ocean destination. Safety comes from conservative decision-making, good surface signaling, and choosing operators with strong procedures for currents, wildlife, and changing conditions. Conservation is central: follow Azores codes of conduct and treat wildlife encounters as passive, controlled experiences.

Top Risks

  • Primary risk: Atlantic swell and surge
  • Secondary risk: Blue-water ascents on banks
  • Emergency contact: Emergency number (Portugal) (112)
  • Safety overview: Faial is an openocean destination.

Dive safety

Plan for Atlantic variability. Use an SMB on boat dives and be ready for drift-style profiles. Keep dives conservative if you have an offshore crossing, and do not push no-decompression limits. For caves and caverns, only enter with appropriate training, redundant lights, and a guide who knows the site. If seas are rough, accept call-offs and switch to sheltered dives or topside plans.

The Central Group hyperbaric chamber is located on Faial at Horta Hospital. In a suspected DCS case, call emergency services (112), provide 100% oxygen if available, hydrate if the diver is conscious, and arrange transfer in a horizontal position as advised by local guidance. Keep your dive insurance details accessible.

Snorkel and freedive safety

  • Atlantic swell and surge

    Even sheltered sites can surge when swell wraps around the island. Avoid rocky entries in breaking seas and trust local call-offs.

  • Blue-water ascents on banks

    Offshore dives can lack a visual bottom reference. Stay with your guide, use a DSMB plan, and avoid solo ascents.

  • Thermoclines and exposure risk

    Temperature can change quickly with depth. Dress for the coldest part of the dive and for long surface intervals in wind.

  • Seasickness on long crossings

    Seamount days can mean hours at sea. Consider medication, hydrate, and eat light before departure.

Wildlife and protected areas

Faial diving is closely tied to wildlife tourism and marine science. Follow the Azores Diving Code of Conduct:

  • Do not touch, feed, or chase animals.
  • Do not collect souvenirs (shells, rocks, artifacts).
  • Keep fins and gauges off the bottom, especially around sponges and gorgonians. For shark dives, follow the regional shark-diving code of conduct: stay with the group, keep movements slow, and let the operator control baiting and spacing. For whale and dolphin trips, respect regulated approach distances and time limits, especially when calves are present. Choose licensed operators and accept conservative decisions when animals show avoidance behavior. The Azores is expanding marine protected areas, so expect site-specific rules and no-take expectations.

Do Not Do This

Avoid entering when atlantic swell and surge. Confirm local briefings before committing.
