How to Dive Safely: 10 Stages from Sitting Dive to Standing Dive

Diving is a fun skill and part of competitive swimming, but diving into water that is too shallow can cause life-changing neck injuries. Learn it slowly, in deep water, with a coach.

Learning to dive step by step: only in deep water where diving is allowed, then a sitting dive, kneeling dive, crouch dive and standing dive — The dive progression, always in deep water

Safety first: never dive head-first into shallow water, water of unknown depth, or anywhere with a "No diving" sign. Most serious diving injuries happen when the head hits the bottom in shallow water. Many water safety organisations, including the American Red Cross, advise a depth of at least about 2.7 metres (9 feet) for head-first entries from the side. Learn to dive with a qualified coach.

Before you start

You should be able to swim confidently in deep water, surface calmly and swim to the side. Most public pools in Singapore restrict diving to designated areas; follow the signs and lifeguards' instructions. Condo pools are often too shallow for diving, so check the depth markings and rules, and if in doubt, do not dive.

The 10 stages

Check the water. Confirm that diving is allowed, the depth is marked and deep enough, and nobody is swimming in front of you.
Practise the streamline. Arms overhead, hands stacked, head between your arms. Your hands and arms protect your head as you enter. See our streamline guide.
Push and glide underwater. From the wall, push off in streamline and steer gently up to the surface by lifting your hands. This teaches you to control your path underwater.
Sitting dive. Sit on the edge of the deep end with your feet on the gutter or wall. Make a streamline, tuck your chin, lean forward and roll in hands first.
Kneeling dive. Kneel on one knee at the edge with the toes of the front foot curled over the edge. Streamline, aim your hands at a point in the water a little in front of you, and tip forward.
Crouch dive. Stand with both feet at the edge, toes curled over, knees bent low. Streamline and roll forward, pushing gently with your legs as you go.
Standing dive. From a slightly bent standing position, swing your arms forward, push with your legs and spring outwards, entering hands first through one point in the water.
Steer up early. As soon as you enter, lift your hands and head slightly so you glide towards the surface, not the bottom. This is the most important safety habit.
Add a glide and kick. Hold streamline, then kick to the surface and start swimming.
Refine with a coach. Competitive racing starts from blocks are taught separately, in pools deep enough for them, under supervision.

Common mistakes

Belly flop: going out flat instead of entering hands first. Aim for one small "hole" in the water for your whole body to go through.
Head up: looking forward at entry. Keep your head between your arms.
Diving too deep: steer up with your hands soon after entry.
Arms apart: keep your hands locked together to protect your head.

Diving and SwimSafer

Entering the water safely is part of water safety training, and programmes such as SwimSafer progress through safe entries as children advance. Children should learn any head-first entry under an instructor's supervision, in water deep enough for it. See our SwimSafer course page.

Never dive

into shallow water or the shallow end of a pool;
into the sea, a river, a lake or any water where you cannot see the bottom;
after drinking alcohol;
where there are "No diving" signs or swimmers in front of you.

If someone may have hurt their neck in the water, keep them still, call 995 for an ambulance, and get help from a lifeguard. Read our water safety tips.

Learn with a coach

A coach will make sure you practise in water of the right depth and progress only when you are ready. See our kids swimming course, adult swimming course or private swimming course.

Frequently asked questions

How deep should the water be for diving?

Many water safety organisations, including the American Red Cross, advise at least about 2.7 metres (9 feet) for head-first entries from the side. Always follow pool signs, and never dive into shallow water.

Can I dive at a condo pool?

Many condo pools are too shallow for safe diving. Check the depth markings and condo rules; if diving is not clearly allowed and the water is not deep enough, do not dive.

What age can children learn to dive?

Children can learn sitting and kneeling dives once they swim confidently in deep water, under an instructor's supervision.
