Sport envelope last vs now
Pin last versus this reading of the depth, risk and skill marks already published on this sport.
Teaching envelope — not a dive clearance or a safe-today stamp.
Snorkeling skill, risk, and depth - teaching envelope
Are the skill, risk, and depth marks a dive clearance?
No. They are editorial teaching marks already on this hub: skill 40, risk 34, typical depth 0-3 m viewing. The envelope pins last versus this reading. It is not a shop briefing or a safe-today stamp.
What does the 0-3 m viewing band decide?
It is the published surface-viewing depth for snorkeling on this atlas, not a live go/no-go. Current, boats, and park flags sit in the safety chapter.
Do I need a scuba agency card to snorkel?
This hub's quick facts say none required. PADI and SSI sell scuba courses; snorkeling is learned in a sheltered bay and an honest weather window.
What is last versus this envelope for?
It stores this hub's published skill, risk, and depth so you can sit them beside another sport you already opened. Compare marks. Do not treat the pair as clearance.
Snorkeling viewing-band decision once
A numbered pass on Snorkeling skill, risk, and the published 0–3 m viewing envelope — not dive clearance.
- Read the skill mark — Skill ceiling on this hub is 40/100 — editorial teaching, not a skills test score.
- Read the risk mark — Risk is 34/100 here. It compares topics in the atlas; it is not a live hazard bulletin.
- Depth band 0–3 m is viewing — Typical depth published as 0–3 m viewing is surface viewing band, not a go/no-go clearance.
- No agency card is issued here — Nothing on Snorkeling replaces a shop briefing, flag check, or scuba agency card. Close if you need certification advice.
On Snorkeling, skill 40, risk 34, and 0–3 m viewing are the three honest envelope marks before you open the atlas points.
Teaching envelope only. Not a dive clearance or safe-today stamp.
Depth and safety second decision once
After the viewing-band pass on Snorkeling, read depth beside the safety chapter marks — still not dive clearance.
- Re-read the published depth band — Typical depth stays 0–3 m viewing. It is a teaching envelope, not a go/no-go stamp for today.
- Open the safety chapter next — Use the safety section as the second decision card. Shop briefings and flags stay off this page.
- Read accessibility as a band mark — Accessibility is 86/100 here — relative atlas teaching, not a skills test or agency grade.
- Risk still is not a live bulletin — Risk remains 34/100. Pair it with depth and safety text; nothing here replaces a site briefing.
On Snorkeling, 0–3 m viewing, access 86, and risk 34 are the honest second-pass marks after the viewing band.
Teaching envelope only. Not a dive clearance or safe-today stamp.

Depth check
A planning aid. Not a certification or a forecast.
Snorkeling is surface swimming with a mask and a J-shaped tube so the face can stay in the water. It is not scuba, not freediving, and not a certification sport — though poor fins and a leaking mask make it look harder than it is.
The wow factor in this atlas is high because a healthy reef in two metres of water outruns many deeper dives. Risk sits in the middle: sun, boats, current and panic, not decompression. Seasonality follows wind, monsoon and jellyfish more than a federation calendar.
This chapter is a craft and site map. It is not a live snorkel briefing and not a ticket from PADI or SSI. Those agencies sell scuba courses; snorkeling is learned in a sheltered bay and a honest weather window.

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.
How is this different from freediving?
Freediving is intentional breath-hold depth. Snorkeling is surface breathing with optional brief ducks. The freedive chapters cover blackout risk.
What does “snorkelling” vs “snorkeling” mean?
The same activity. British English prefers the extra l; this atlas uses the Wikipedia title Snorkeling.
Can children snorkel?
In warm, still, shallow water with touch supervision and a mask that fits. A full-face gadget is not a teacher.
Why do masks fog?
Spit or a drop of baby shampoo on a clean lens; toothpaste “scrub” myths scratch coatings. Rinse after sunscreen hands.
Are full-face snorkel masks a good idea?
They have a documented CO2 and panic problem in some designs. A conventional mask and snorkel remain the standard.
Do people need fins?
In any current or for a long swim, yes. In a waist-deep lagoon, they are optional and can damage coral if the wearer kicks down.
Is this medical or a dive briefing?
No. Conditions, boats and park rules are local and daily.
