Underwater Hand Signals Every Snorkeler Should Know
The essential hand signals for snorkelers: OK, problem, up, down, look and come here — communicating clearly when heads are underwater.

With faces in the water, snorkelers cannot talk — and shouting at the surface over waves rarely works either. A dozen simple hand signals cover nearly everything a group needs.
The Core Five
• OK — thumb and forefinger in a circle, or a flat hand rocking side to side at a distance
• Problem — flat hand rocking, or point at the problem then rock the hand
• Up / go up — thumb up
• Look here — point two fingers at your eyes, then at the target
• Come here — palm toward yourself, fingers curling twice

Group and Safety Signals
• Are you OK? — point at a person, then show the OK sign and raise eyebrows
• Watch out — flat hand cutting across the throat is the universal stop signal in water
• Help — waving both arms overhead at the surface is the international distress sign; reserve it for real emergencies
Agree signals before entering the water, especially with mixed groups and kids. A short briefing on the beach prevents the classic confusion between OK and waving.
Signals Meet Equipment
Signaling works best with the right gear: a bright snorkel or mask helps the group keep visual contact, and a whistle on a float carries farther than any arm wave. For surface marking, see flags and floats; for keeping weaker swimmers comfortable in a group, see flotation options.
Teaching Kids the Signals
Kids learn the five core signals in two minutes when you make it a game — ask them to show OK, up and come here before the swim starts. Our kids snorkel guide covers the rest of the safety briefing.
