If you only read one thing
The rulebook that sits under every snorkel and dive — no standing, no chasing, no souvenirs, and why parks now say it in five languages.

Read first Water sports carry drowning, pressure and medical risks. Use certified instruction, check conditions, and never treat depth or time tables as personal clearance.
How to use this guide Match skill to site Start in controlled water, then add current, depth and night only with training.Verify agency path PADI, SSI, CMAS and national programs differ on medical and depth rules.Expert voices Conditions beat gear: abort early when visibility, current or buddy signals change. Dive instructor — Site briefings Quick answers Do I need a medical form? Most agencies require a questionnaire or physician clearance before confined or open-water training.
How do seasons affect sites? Visibility, current, temperature and wildlife access change by month — check local charts and operators.
Key data Band Teaching use Depth band Agency training limits — not a personal clearance. Visibility Site and season dependent; abort when buddy contact is lost.

Shop briefing Day-of local constraints from clubs and charters. Local examples Federation lane rules Reef permit windows Local FAQ Is this a dive briefing? No — verify coastguard/federation and shop rules for the day.
Why do season windows matter more than ratings? Visibility and permits shift; envelopes beat permanent scores.

Can I copy a site’s depth for my plan? Treat listed depths as teaching envelopes. Real plans need charts, guides and conditions that day.
Buddy requirement? Recreational systems usually train with a buddy. Solo requires extra training and local permission.

Reef etiquette is the shared conduct layer for snorkeling, scuba and freediving on living coral and in seagrass. It is written by parks, customary owners and a few national statutes — not by a training agency’s marketing slide.
The skill ceiling is low on purpose: the rules are simple and the failures are expensive in centuries of coral growth. Accessibility is high because anyone who can enter the water can also choose not to kneel on a colony.
This chapter is not a live briefing and not a permit. Local rangers, mooring fees and seasonal closures override any atlas sentence.
Educational atlas, not a certifying agency and not medical or rescue advice. Local parks, skippers and instructors have the last word on conditions.

Frequently asked questions Which local rescue or training agency should I check first? Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
Is touching coral always illegal? Often yes in a park, and always a bad idea. A glove does not make a polyp tougher.
Why do Hawaii and Palau restrict sunscreens? Statutes target ingredients such as oxybenzone. The science and the politics are both live; long sleeves work regardless.
Can people take a shell? In many countries, even empty shells and sand are restricted. Assume no souvenir.
How far from a turtle? Many parks specify 2–3 metres or more, no blocking the surface path. If the animal changes direction, the person is too close.
Is feeding fish kind? It changes behaviour and is banned in serious parks. The bread-ball boat is a failure mode.
Does a good photo need a chase? No. The chase is how people kick coral and stress animals. Parks now fine it.
Is this a certification? No. It is conduct. A card that says otherwise is marketing.
