Rip Currents Statistics

T/ F What are the chances of drowning at a beach protected by lifeguards affiliated with the United States Lifesaving Association (USLA)?

  • One in 2 million

  • One in 18 million

  • One in 23 million

  • One in 50 million



Rip currents l.jpg
Rip Currents

Rip currents account for over ___% of rescues performed by surf beach lifeguards.

  • 20 %

  • 30%

  • 70%

  • 80%



Rip current formation l.jpg
Rip Current Formation

Deceiving, it looks like a nice calm area:



Rip current formation14 l.jpg
Rip Current Formation

What is the correct sequence of rip current formation?

  • Wave travels to the beach, waves break on sandbars, water runs off beach through a channel.

    B. Waves break on sandbars, wave travels to the beach, water runs off beach through a channel.

    C. Water runs off beach through a channel, wave travels to the beach, waves break on sandbars.

    D. None of the above.


B waves break on sandbars wave travels to the beach water runs off beach through a channel l.jpg

B. Waves break on sandbars, wave travels to the beach, water runs off beach through a channel.


Rip current formation16 l.jpg
Rip Current Formation water runs off beach through a channel.

The longer the period between waves:

a. The more energy in the the waves.

b. The faster the waves move.

c. The more momentum the waves carry.

d. A and B

e. A,B, and C


E a b and c l.jpg

E. a, b, and c water runs off beach through a channel.


Rip current formation18 l.jpg
Rip Current Formation water runs off beach through a channel.

__________ is proportional to amplitude or height squared


Wave energy l.jpg

Wave energy water runs off beach through a channel.


Rip current formation20 l.jpg
Rip Current Formation water runs off beach through a channel.

When do rip currents become most dangerous?

a. During high surf conditions as the wave height and wave period increase.

b. During low surf conditions as the wave height and wave period decrease.

c.During high surf conditions as the wave height and wave period decrease.

d. During low surf conditions as the wave height and wave period increase.


A during high surf conditions as the wave height and wave period increase l.jpg

a. water runs off beach through a channel.During high surf conditions as the wave height and wave period increase.


Types of rip currents l.jpg
Types of Rip Currents water runs off beach through a channel.

  • This type of rip current is short in duration (less than 10 minutes)

    • Enhanced by large swells with more wave energy and volume.

    • Unpredictable temporary conditions and variable locations.


What is a flash rip current l.jpg

What is a Flash Rip Current? water runs off beach through a channel.


Types of rip currents24 l.jpg
Types of Rip Currents water runs off beach through a channel.

  • This type of rip current develops along jetties, piers, and groins.


What is a permanent rip current l.jpg

What is a Permanent rip current? water runs off beach through a channel.


Types of rip currents26 l.jpg
Types of Rip Currents water runs off beach through a channel.

  • This type of rip current is dependent upon shape of coast, bays, points, reefs or sand bars.


What is a fixed rip current l.jpg

What is a Fixed rip current? water runs off beach through a channel.


Types of rip currents28 l.jpg
Types of Rip Currents water runs off beach through a channel.

  • This type of rip current occurs with long shore (parallel to beach) current.

  • Pushes rip away from original location and weakens it.


What is a traveling rip current l.jpg

What is a Traveling rip current? water runs off beach through a channel.


Types of rip currents30 l.jpg
Types of Rip Currents water runs off beach through a channel.

A long shore current may push swimmer into:

  • Flash rip current

  • Permanent rip current

  • Fixed rip current

  • All of the above


D all of the above l.jpg

D. All of the above water runs off beach through a channel.


Rip currents safety l.jpg
Rip Currents Safety water runs off beach through a channel.

T/F Rip currents do not pull people under the water—they pull people away from the shore.

T/F Undertow and riptides are the same as rip currents.


False l.jpg

False water runs off beach through a channel.


Rip currents safety36 l.jpg
Rip Currents Safety water runs off beach through a channel.

T/F Rip currents only occur on beaches near the ocean.


False they also occur in the great lakes l.jpg

False, they also occur in the Great Lakes. water runs off beach through a channel.
