Dive Safety Essentials

• Check swell and wind direction daily. If an ocean-facing entry looks rough, switch to a sheltered bay.
• Use an SMB on boat dives and any drift-style ascent. Brief your deployment method with the guide.
• Stay conservative on gas and no-decompression limits. Cold water and surge increase consumption.
• Keep your ascent and safety stop tight to the group. Do not drift into boat lanes.
• For freediving and snorkeling, always use a buddy system and a highly visible float.

Common Local Hazards

• Thermoclines: deeper water can feel much colder than the surface, especially Jun to Sep.
• Surge on rock: protect hands and knees, and avoid narrow swim-throughs if swell is running.
• Fishing line: keep distance from lines and markers, and carry a line cutter (scuba).

Operator Choice

Choose operators that brief site rules, protected-area protocols, and emergency procedures clearly, especially if you are doing an Arraial do Cabo RESEX day trip.

Medical Planning

• Carry dive accident insurance (DAN or equivalent) and keep policy details accessible offline.
• For serious emergencies in Brazil, the public ambulance number is 192 (SAMU). Police is 190 and fire/rescue is 193.
• For suspected DCS: stop diving, give 100% oxygen if available, keep the diver warm and hydrated (if conscious), and contact DAN for medical coordination and chamber referral guidance.
• Bring your own essentials: any prescription meds, a small first-aid kit, seasickness medication for boat days, and hydration salts.

For non-emergency issues, private clinics can be faster than public services, especially during busy holiday weeks.
