Using a Snorkel at the Surface

A snorkel is a basic tool used for breathing face-down at the surface without using tank gas. While it has its place in diving, its real-world usefulness is limited — and in many conditions, it’s better left unused.

When a Snorkel is Useful

• Flat, calm water with no chop or swell
• Long surface swims during shore entries or exits — especially when you want to keep your regulator dry or preserve dive computer battery life
• Training environments where skills like mask removal or snorkeling are practiced on the surface

In these cases, a snorkel can help you stay streamlined and breathe efficiently without touching your tank.

When Not to Use a Snorkel

• Choppy, wavy, or surge-prone conditions — even small surface waves can easily flood a snorkel
• Boat entries and exits — a snorkel gets in the way and can snag on straps or bump the tank
• When wearing a full-face mask or diving in technical gear — many snorkels aren’t compatible and provide no benefit

Trying to force a snorkel into your routine in the wrong conditions just creates unnecessary complications.

Regulator vs. Snorkel: Make the Safe Choice

Some divers are taught to switch to a snorkel at the surface to “save air,” but this is outdated thinking. The gas you use at the surface is minimal, and safety and control come first.

Use your regulator when:

• You're in any kind of surface chop, surf, or swell
• You’re tired or winded from a dive or surface swim
• You might need to descend without delay
• You're dealing with current or poor visibility

The regulator gives you the most secure breathing method — no clearing, no flooding, no surprises.

If You Choose to Use a Snorkel

• Keep it simple: If you bring one, make sure it’s compact and stays out of the way
• Don’t overthink stowage: A basic J-style snorkel works fine if you’re diving in calm water and actually plan to use it — otherwise, skip it
• Know how to clear it: If you do use a snorkel, be ready to forcefully exhale to clear water — and don’t inhale until you're sure it’s clear

Common Mistakes

• Using a snorkel in rough conditions — increases your risk of inhaling water and losing composure
• Switching from reg to snorkel too early — when you're still recovering from a dive or not fully stable
• Carrying a bulky snorkel that constantly gets in the way — choose something simple or leave it behind if it’s not worth the hassle
