* Low Risk of rip currents - Strong currents can still occur near
jetties and reef channels. Always have a flotation device with you
in the water.

Moderate Risk of rip currents - Wave conditions support stronger or
more frequent rip currents. Always have a flotation device with you
in the water.

High Risk of rip currents - Large waves will produce strong rip
currents, especially along narrow reefs and beaches. Rip currents
will be life threatening. If caught in a rip current, swim parallel
to the beach rather than against the current.

Low tide often exposes the sandbars and channels that shape rip currents, and the risk can run higher for an hour or two either side of it. Full tide table for Pago Bay, Guam.

Times are Chamorro Standard Time. Lifeguards are off duty outside posted hours, and the rip current risk does not fall with the light.

What this means

The three levels the National Weather Service issues, and what to do at each.

HighLife-threatening rip currents are likely. The surf zone is dangerous for swimmers of every level. Stay out of the water.
ModerateLife-threatening rip currents are possible. Swim near a lifeguard, and follow the beach patrol and its flags.
LowLife-threatening rip currents are not expected, but they can still form near groins, jetties, reefs and piers. Swim near a lifeguard.

If a rip current carries you out

  1. Do not fight the current. It pulls you away from the beach, not under the water.
  2. Stay calm and keep your head above water. Float or tread water until the pull eases.
  3. Swim parallel to the beach, along the shore, until you are out of the current, then angle in toward the beach.
  4. If you cannot escape, face the shore, wave your arms and call for help.
  5. If someone else is caught, do not go in after them. Get a lifeguard, call 911, and throw them something that floats.

Thunderstorms and lightning

Thunderstorms build fast over water on a summer afternoon. Water and open sand leave you the tallest thing around. When thunder roars, go indoors: leave the water and the beach for a building or a hard-topped vehicle, and wait 30 minutes after the last thunder before going back.

A rip current is a narrow stream of water flowing away from the beach, through the surf and past the breakers. It pulls swimmers out, not under. Rip current and lightning safety guidance from the National Weather Service.
