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.

Season window Vis, swell and permit timing beat permanent scores.
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.

Night diving is recreational scuba after the reef goes dark. Parrotfish sleep in mucus tents, crustaceans walk, and a torch beam becomes the only map. The wow factor is high; so is the risk score — disorientation, boat traffic and a lost buddy are easier after sunset.
A night dive is not a first dive, not a wreck-penetration plan, and not a freedive. Kona’s manta night dives and Red Sea night reefs are famous because operators run tight lights-and-buoy systems, not because darkness is inherently safe.
This chapter is orientation. It is not a briefing, not a certification, and not medical advice. The day’s wind and the boat’s light rules win.
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 risk scored near wreck diving? Lost buddy, boat props, and disorientation show up in incident literature. Combining night with wreck or cave is worse.
What is the Kona manta night dive? A well-known Hawaii product: lights on the sand attract plankton, then mantas. Distance rules are the etiquette.
How many lights? A primary and a backup is the usual teaching. A tank-marker or stick light helps the boat.
Do people need a specialty card? Not legally in most places. Shops may require one or a minimum log count.
Is a full moon easier? More ambient light, different animal behaviour. Not a safety system by itself.
Certifying agency? This page is not one.
Medical advice? No.
