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.

Why do season windows matter more than ratings? Visibility and permits shift; envelopes beat permanent scores.

Buddy requirement? Recreational systems usually train with a buddy. Solo requires extra training and local permission.

Freedive safety is a culture: a watching buddy, a conservative turn, no hyperventilation, and a surface protocol that lasts until the diver is clearly themselves again. Shallow-water blackout — loss of consciousness from hypoxia, often near the surface — is the distinctive hazard.
Wow factor is low on purpose. This chapter exists so the freediving topic does not have to carry the whole argument. Risk remains high because the physics does not care about a holiday mood.
This is not medical advice, not a rescue certification, and not a live dive plan. AIDA and national bodies publish safety regulations for competitions; clubs copy the useful parts. Courses teach the hands-on skills this atlas will not.
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.
Why is hyperventilation dangerous here? It lowers carbon dioxide, which is part of the urge-to-breathe signal, without adding a matching oxygen store. Courses treat it as a blackout setup.
Is a scuba buddy enough? A scuba diver on a regulator is not automatically a freedive safety. The roles differ. Train together or do not depth-dive.
Do competitions have safety teams? AIDA events specify safety freedivers, oxygen and protocols. Recreational bays do not, unless a club brings them.
Can this page teach rescue? No. Rescue is a contact skill with legal and medical pieces. Take a course.
Is samba the same as blackout? Loss of motor control at the surface is a warning state courses name and treat as an emergency. This page will not teach the differential.
Solo spearfishing? A real culture and a recurring fatality pattern. This atlas will not romanticise it.
Medical advice? No. Heart, lung and equalisation questions are clinical.
