What is a breakthrough current and how is it a significant factor in drowning cases at sea?

A rip current is formed when waves coming from the southwest hit the coastline, return towards the depth of the sea in a relatively straight line and cause the formation of a channel. The more powerful the wave, the deeper the channel that is formed and the harder it will be to get out of.

The rip current sweeps into the sea whoever gets caught in it. He will continue to sweep until after the crisis line.
The higher the waves, the stronger the rip currents. An experienced swimmer, however experienced, is unable to swim against the speed of a strong rip current. Therefore, those caught in a rip current should swim to the side and not against it.

In many drowning cases, the swimmers try to swim against the current, until they lose strength. All this in the area of ​​the crises that are crushing them.

Bathing under the supervision of a lifeguard - saves lives:

The lifeguards are very experienced in identifying rip currents on the beaches.
They demarcate the area of ​​the rip currents, whose position changes throughout the day (the sea is dynamic, remember?), by placing black flags that indicate to bathers the limits of the area allowed for bathing.

  1. Thank you from the bottom of my heart, I was smart, I didn't know this information. Very helpful.
    Thank you again.

  2. Many thanks to all the corresponding authors.
    Just to be clear, on clear winter days there are underwater records of rip currents that exist permanently in the same places and are very long, later we will mark them and publish them. Safe summer for everyone.

  3. Hello Avi. You are right, there was a typo and thank you for the important attention.
    The rip currents move perpendicular to the shore.
    Although I paid exceptional events because of a low island that formed on the student beach and the current curved northward and returned to being vertical until it stopped in shallow water some distance from the beach.
    If you want, contact me privately so as not to confuse the readers with an unusual phenomenon that is actually harmless in a calm sea compared to the standard one.

  4. An article with high added value that can save people from drowning if they read the article.

  5. Hello Albert.
    There are rip currents that are so powerful and wide and stretch for a long distance from the beach...Banana Beach

  6. Hello Roni, the channel is formed parallel to the shore and waves do not break in such a current.
    And it's our luck, that this is how you can distinguish them.

    • From the article I actually understood that the canal was perpendicular to the shore and that's where the drift flowed to the depth of the sea.
      So what is true?

  7. Hello Rebecca, for your information..
    There are places in the world where after a certain hour there is no access to the sea.
    And there is a difference between entering such a stream at night and entering during the day.
    The student beach, for example, is known for many hacking trends.

  8. Experienced swimmers never swim against the currents. They know it is useless and drains the forces which causes drowning.

  9. In rip currents there is no point in swimming towards the shore, these are only to the sides, trying to swim towards the shore is a waste of energy since the waves come back and create a kind of trench between waves which looks quite scary and threatening, therefore swim only to the sides

  10. What can be done to have lifeguards only during the hours of the Israeli sun that burns, dazzles, hits with heat, dries, and causes cancer?
    Is it not possible to provide lighting for the early morning hours and at night so that lifeguards will be able to identify the dangers at sea even in the hours of darkness?

  11. An important article my friend Motty Mendelson. good week

  12. It's true Tomer, but it's a health issue that can also happen on the street.
    And in a completely calm sea

    • Even the swimwear or actually the lack of modern swimwear today damages the concentration of swimmers who play it heroes and then oops they drown too

  13. Do you know what else causes drowning in the sea? Sudden cardiac arrest. or a stroke.
