Dive safety
- Deploy an SMB on drift or channel exits.
- For Blue Hole, dive AOW-only with recent experience, stick to guide depth and time, and stay hydrated on the long ride.
- Seas can be rough on atoll days. Take motion meds and secure gear.
- Log emergency numbers in your phone and on your slate.
San Pedro hosts hyperbaric facilities with 24-hour on-call coverage for dive emergencies. Call local 911 for immediate assistance and coordinate with the chamber staff and your operator. DAN coverage is strongly recommended.
Snorkel and freedive safety
Channel currents and surge
Reef cuts funnel water. Stay within guide range, deploy SMBs, and avoid pushing limits near the crest.
Choppy atoll crossings
Windy days make long rides rough. Take sea-sickness meds and consider moving your Blue Hole day if forecasts deteriorate.
Sargassum season
Floating seaweed can affect eastern beaches seasonally. The leeward side and Secret Beach stay clearer most days.
Wildlife and protected areas
- Hol Chan zones prohibit gloves and touching coral. Shark Ray Alley remains snorkel-only with supervised shark feeding from boats by licensed guides.
- Mexico Rocks includes no-take areas. Observe moorings rather than anchoring and keep fins off the bottom.
- Sport fishing is regulated and catch-and-release licensing is enforced.
- Use reef-safe sunscreen and avoid standing on coral or seagrass.
Do Not Do This
Avoid entering when channel currents and surge. Confirm local briefings before committing.
