At some beaches, the backflow does not flow seaward, it runs along the coast. It's
usually narrow, horizontally between 1-3m, some others maybe has the horizontally
over tens of meters wide, the average velocity of 0.5-1.0 m/sec, faster than the speed
of human swimming.
Backflow is the cause of most cases of rescue and drowned while bathing in the
world. The reason is that it pulls people swim away from the shore, making
exhaustion swim drowned in a panic and exhaustion while trying to swim against the
flow.
For those who can not swim, backflow can pull they further away whether they was
standing in water only waist. Then people will not swim may panic and drown.
What is more dangerous is where the backflow formed the water often flat, little
thought waves so visitors often come here and swim ignore hazard warnings, then
they will immediately be swept away into the sea.
How to recognize the backflow: Before swim, visitors should take about 5-10
minutes to observe the sea. Backflow often brings the following characteristics:

How to get out of the backflow: Actually, backflow does not take people into the
water, it just pulls swimmers away from shore, and then pushes swimmers to the
area has waves hit the shore.
However, people often fall into the drowning backflow because of the nature of
people that trying to swim against the flow to the shore, exhausted and quickly lead
to drowning.
Besides, the panic that make swimmers are no longer accurate judgment. Therefore,
it is more important that crashed into the backflow is to be calm, do not try to swim
against the flow. If confident, visitors swim parallel to the shore, often it can bring
swimmers to the waves hitting area and then visitors can swim to the shore. For
weak swimmers: When can not touch the bottom of sea or feeling out of weakness,
raised hand as signaling, calm down, float to keep the power then call for help.
Also, if the backflow is weak, try to swim parallel to the shore to get the waves hitting
area.
Remember that backflow can cause danger at any time, not just when a big wave.
