Rip currents are dangerous mainly because they can sweep swimmers away from shore much faster than most people can swim, and they often appear calm at first, making them easy to enter by mistake. Their strength and speed can vary dramatically, and a swimmer who panics or tires can become exhausted and drown before reaching the shore. In addition, the current does not pull people under; it carries them seaward, which can lead to dangerous situations if the person then tries to swim directly back to shore against the current. Key risks and why they’re dangerous:

• Speed and strength: Rip currents can reach speeds that exceed the swimming ability of many beachgoers, including some strong swimmers, increasing the risk of exhaustion or drowning.

• Subtle appearance: They often look like ordinary, flat water or a calm patch between breaking waves, causing people to underestimate the danger and enter the current unknowingly.

• Perceived control panic: Facing a strong, fast-flowing current can trigger panic, leading to ineffective swimming or ditching attempts, which worsens the situation.

• Offshore pull and distance: The current carries swimmers away from shore, sometimes hundreds of meters or more, increasing the distance to safety and the time needed to escape or be rescued.

• Limited opportunities to escape: The recommended strategy is to swim parallel to the shore to escape the current, then return to land, rather than fighting the current directly or attempting to swim straight back, which can be exhausting.

Practical tips to stay safe:

• Learn to spot rip currents: Look for channels of darker, stained, or choppier water and areas where waves don’t break as expected; they can form where water returns seaward through a gap in the surf zone.

• If caught, don’t fight the current: Float and conserve energy, and swim parallel to the shore toward a safe exit point; once free of the current, swim diagonally back to the beach at an angle away from the current’s path.

• If you’re with others: If someone is in trouble, call for help and throw rather than enter the water yourself; keep others in sight but avoid creating more hazards in the water.

• Heed local guidance: Pay attention to lifeguards and posted warnings, as local conditions can change quickly.
